Re: [CentOS] [PROVENANCE INTERNET] Re: Missing packages in centos8 mirrors or do I miss something?

For those who come across this thread, I've found the exact list of changed and dropped package between rhel:7 and rhel:8:

<a href="" title=""></a>

Too bad that the "note" column is empty in the dropped package table. NO word about reason or possible alternatives.
Also too bad that those drops were not advertised before release so developers could think about migrating there code.

Any ETA for the cloud-images?


I see they are being built, but they can't be accessed directly.


Missing packages in centos8 mirrors or do I miss something?


I need to port OSCAR Cluster and SystemImager softwares to centos8, but I miss a lot of package that seems to be built for centos-8.
For example, I cant find docbook-utils and docbook-utls-pdf while I see them here: <a href="" title=""></a>

I’ve installed epel-release and elrepo-release and centos-release-stream.

Do I miss something or is it a matter of time due to mirro syncs?

I misse btrfs packages, perl-Tk packages, docbook packages and many more that I can find on <a href="" title=""></a>

Where am I wrong?

PS: I’m running CentOS-8 in

USB of ISO image


I did the dd iso to my USB. all is fine.
I can mount the second partition (which is not iso 9660) and edit the
grub.cfg file.
Question is what do I run after that so my new menu option appears ?

grub2-install /dev/sdd

Is that the correct command to get grub to notice my new file ? Assuming
sdd is the USB disk of course.

How to dump/restore a CentOS 7 system

Hello All,

I guess it is very common for administrative purpose, to dump and restore a CentOS 7 system. I usually use dump/restore commands. However, I’m having trouble to handle installing bootloader and creating initramfs for C7 system. Does anyone know a good document source that details those procedure?
Thank you,

Centos 8 Mate?

Without wanting to sound too pushy, I'm wondering if there is any update on the status of Mate now that Centos 8 has been released?

I would love to jump on C8 and start playing with it, but the lack of Mate is kind of a showstopper for me at the moment.

CentOS 8 Everything

HI All - Great work on 7.7 and 8.0!

Will there be a "Everything" iso coming ? perhaps just not sync'd yet on

Does 7.7 support an upgrade to 8 path ?

Thanks! all great stuff.


CentOS 8 Boot.iso image DHCP4 not working?

I'm just wondering if anyone else is not getting a DHCPv4 address in Anaconda, using the CentOS 8 Boot.iso image? I get an IPv6 Autoconfig address, but it doesn't want to pick up a DHCPv4. This is in a Hyper-V Gen2 VM, connected to the same network all my other dev VMs are on, and picking up DHCPv4 without issue.

And, congratz to the CentOS team on 2 releases in a week (or so)!

CO 7.7.1908 Updates not getting to mirrors?

I *know* there has been a lot going on, and congratulations on getting
CentOS 8 out!

But(!), I don't see any updates to CO 7.7.1908 in the "updates" directory

Is something broken?

updates repo for 8

I've checked a couple of mirrors and itself and I don't see updates for the 8 repos yet. Is there a new location for updates now that we're seeing the 8 repos or do I just need to wait for the repos to get a chance to synchronize fully?

Video projector vs. onboard video card


I have a CentOS 7 desktop client installed on an old Dell Optiplex
computer with an Intel video card integrated into the motherboard. The
card has a single VGA connector, and the 19" monitor is connected to it.

I wonder how I could connect a video projector to this computer while
keeping the monitor, in a mirroring configuration, e. g. output is the
same on the video projector and the monitor.

Do I have to replace my onboard video card by something like an NVidia
GT710 graphic card with two video connectors ? Or is there a different
solution for this?

Brother HL-L2360DW printing quality

I have the above printer but have not been able to resolve issues with the printing quality in CentOS 7. The test page prints fine but when I print PDF-documents, most recently using Chinese fonts, it is lacking and the pages very hard to read. The settings in the Mate Cups configuration panel are fine and set to 600 dpi, the settings in the printer menu are all OK yet it prints more like maybe 150 or even 75 dpi.

Any suggestion what might be wrong?

selinux reports

Hi all!

I keep getting reports from selinux, like below, and I have no clue
what the app is it's talking about, nor how do figure out if it should
be allowed access or not.

Anyone got any advice to offer?

It says:

The source process: /usr/sbin/xtables-multi
attempted this access: open
on this file: /run/xtables.lock

Having no clue what xtables-multi is, or why or even if it should be
able to open that file, I am at a loss:

should I take action to enable it, or not?

Thanks in advance!


deprecations leading up to C8

Was reading the long list of things being deprecated in the RHEL 8
release notes t'other day, and saw my old friend sendmail on the list.

I've stuck by her because I've learned how she likes to be stroked to
get the best out of her, and quail at the thought of taking on a new
MTA and having to learn it all all over again.

But I guess I'm going to have to, soon or late, probably sooner than
later. :(

Can anyone point me to resources specifically for helping us ignorant
folk in converting all the arcan-ity in into something
equivalent for Postfix?

Thanks in advancce!


running init disconnects ssh session

Noticing a new behavior lately.  Logged in via sshd and ssh keys as root
to a remote system.  When changing runlevels between multi-user or
graphical the ssh session is disconnected.  It's not a big deal but
annoying if I have other tasks to do on that particular system.  I've
tried logging in as normal user, su to root and it still disconnects the
ssh session upon either an "init 3" or "systemctl isolate" command.

UEFI booting

I installed my first UEFI disk yesterday. Seemed to go fine. CentOS 7.6
I then took that disk "out" of that machine and put it another machine - it
seems to not even boot.
I put the original disk back in that machine and it boots fine.

I put the UEFI disk back in the machine I built it on and it works fine.
They are similar machines either and i3 and i7.

Shouldn't that work? Build a UEFI disk on machine A - move it to machine B?

CentOS7 sometimes don't detect NIC after reboot

I have brand new PC with this components:
CPU Intel® Pentium G5400, LGA1151
motherboard ASUS PRIME B360M-C
HDD 2x ADATA SSD 256GB XPG GAMMIX S11, PCIe Gen3x4 M.2 2280 (RAID1)
NIC Intel X550-T1 Ethernet Converged Network Adapter

I installed CentOS 7 and two NICs were detected:
eno1 (on motherboard)
enp1s0 (Intel X550-T1)

When I restart the machine sometimes enp1s0 is missing. It is not
detected during boot. It looks like NIC card is not installed / not

audit freeing multiple contexts (when running certbot)

Apologies if it's considered off-topic, but I'm not sure in what part
of the system the issue lies.

What about Mate Desktop on Centos 8?

According to Twitter:

<a href="" title=""></a>

"The next version of #CentOS is being released September 24 and will be announced in all the usual places."

I'm wondering about the status of the Mate Desktop.

Looking under M here:

<a href="" title=""></a>

I don't see anything about Mate. Which leads me to ask, what's its status then? I hope it hasn't died since that's what I use for all of my computers.

reconfigure centos-6.9 host to ignore missing nic

I need to work on a host which has been offline and powered down for
some time. I has CentOS-6.9 installed. At some point it had two
nics, one on the motherboard (still present and working) and one as an
expansion card.

When booted the console displays:

pciehp 0000:00:1c:0:pcie04: Failed to check link status


How do I tell the host to ignore the missing nic or remove it from the
system configuration so that the error is removed.

How to disable i915 module

I am setting up CentOS 7 on my new firewall. This will run as a head-
less system, accessed via a serial console when necessary. It's only a
2GB system, so I don't see any reason to have the GPU consuming any of
the RAM.

I've blacklisted the i915, drm, and drm_kms_helper modules and rebuilt
the initramfs, but the i915 module is still being loaded.

Anyone know what might be loading the module and how I can stop it?


RPMDB problem

When doing yum operations I get this message at the end of whatever
yum was doing:

** Found 1 pre-existing rpmdb problem(s), 'yum check' output follows:
brscan4-0.4.8-1.x86_64 is a duplicate with brscan4-0.4.3-1.x86_64

It is true, if I do "rpm -qa | grep brscan" it shows two of them.

what's the best/proper way to deal with this?
-remove both, reinstall one?
-remove one? which one? I don't see a feature in rpm (or yum) for
removing a single one of duplicate packages. How?

Thanks in advance!


conflicts in updating to CR repo

Note, first of all I haven't actually updated, I'm just running "yum update"
to see what conflicts, if any, I get so I can be prepared when the final
7.7 release happens.

I've traditionally used the nvidia packages from elrepo, but recently
enabled rpmfusion (back when I started using 7.x, I disabled rpmfusion
because it took them a looooong time to get a EL7 repository up).

I use the priority plugin in yum, and have elrepo at priority 50
and rpmfusion at priority 60, so the elrepo nvidia packages
should "win", but yum seems to be confused about which packages
to use.

So now when doing yum

File server as host for a Windows Server VM?

I hope that someone here can give some advice on the following:

I have a Samba based Active Directory. A CentOS 7.6 machine runs as a
file server and hosts the Windows user profiles for all the Windows

Now management has decided that they need a Windows server for a couple
of administrative applications, which need MS SQL Server. That would be
the only role of this Windows.

Opinions on using CR repository in production environments.

I was wondering what people's opinions are on running the CR repository on
production systems? I'm currently predisposed to not do it since it
indicates it hasn't fully gone through QA yet. But from my understanding
except for the alt-arch systems these are just recompiles of the redhat
RPMs after debranding right?

I'm Curious how other people are treating this repository since, from the
sounds of it, rpms are going to be in holding here between releases.

So would you treat it as a production repository or for testing only?

Increase logging verbosity of saslauthd?


CentOS 7.X, sendmail.x86_64 8.14.7-5.el7, cyrus-sasl.x86_64 2.1.26-23.el7

There are conflicting message on how to increase the logging of saslauthd.

I know I can do this:
/usr/sbin/saslauthd -d -n0 -m /var/run/saslauthd -a pam

but that requires a terminal as saslauthd logs the output to STDOUT, this is not what I want.

I would like to have it started as a daemon and verbosity of logging increased into a log file.

How can I increase the verbosity of logging for saslauthd?


oval support for centos

We use oval to check the system vulnerability.

Redhat offer official oval(<a href="" title=""></a>), and
it works well on redhat.

There is no official centos oval, and using redhat oval on centos got
false results.
centos is based redhat, so I wrote a script fetch redhat oval files and
convert it to useful for centos.

And I push the oval to my github: <a href="" title=""></a>

Everyone interested in this can try to use it and tell me it works
correctly or not.

clamd / amavisd missing socket

I think something along these lines appeared before
but I was unable to find them.

I'm on a 7.6 system, been running clamav and amavisd-new
since 6 days with little problem. On a recent reboot,
clamd@amavisd does not start up and fails manual start.

The problem seems to be the missing socket that connects
the pair, "/var/run/clamd.amavisd/clamd.socket".

I believe this should be created by systemd files but I
see no indication of them on my system.

Anyone know which files might be missing and where to
get copies?

I broke "yum update" - C7

This evening I decided to do some work on my development C7 system. As I have not touched it for a while, and wanted to install new services I thought I'd better yum update first.

I saw that it only did updates from Google and PHP, and none from the system repo's so I had a closer look.


I used to be able to 'repair' ext4 fs issue (when the boot process drops

both say fatal error

I've posted this on cups forum several days ago but did not receive any suggestion. May be Centos Users/admins could give me some advices.

On the web interface all requests belong to Withheld user and it is difficult to know who is printing and who can cancel his request.

Is there some documentation/tutorial to instruct cups to use a remote ldap server to identify users?

CentOS 5 file system read only issue

Hello Everyone,

We are using CentOS 5 system for certain application. Those are VM guests
running in VMware. There is datastore issue occasionally, causing all file
systems becoming read only file systems. So application stop working, and

reliability to the application so that if files cannot be written,
application should time out. We are trying to use IO::Select to handle

CentOS Amazon Machine Image?

I am totally new to AWS.  There was a posting here ~ a year ago making
claims about setting up a CentOS image on AWS.

I have created a free AWS account and am looking at the available images.

None are named CentOS.  There is a Redhat Enterprise Linux 8 and
Amazon's own Linux and SUSE, Ubuntu, but I don't find CentOS.

This is a learning endeavor.  I was thinking to first set up a BIND
slave for my domain.  Then move on to a http image, then work with
MariaDB.  All to see what I can do with AWS that is familiar to what I
do on my own servers.

Any pointers greatly appreciated.
