cron issue

I've set up a cron job to run logwatch at night.

Output from command /usr/sbin/logwatch --mailto=....

gives:

/var/cache/logwatch No such file or directory at /usr/sbin/logwatch
line 634.

and line 634 is:

opendir(TMPDIR, $Config{'tmpdir'}) or die "$Config{'tmpdir'} $!";

I don't understand what file is missing. I can confirm
that /var/cache/logwatch doesn't exist. Should I just arbitrarily make
one? Is it an install error? I've just installed the system, U18.04, up
to date.

Ideas welcome.

python script aborts on Ubuntu 16.04: No JSON object could be decoded

Hello,

I am trying to run this Python script:

starts but fails with the error message below. The behavior does not
change at all if, instead of reading the data to import from a file, I

Ubuntu Budgie 18.04 automated random key inputs from somewhere on laptop

I've been using ubuntu 18.04 ( budgie ) for my laptop for quite some time. Recently, wierd shit started happening, I would be browsing a website and scroll down and the the webpage would zoom out. Many other such instances happened until I realised that for some reason the Ctrl button input was being given at certain times. Not only that sometimes my mouse right clicks on its own and when I'm browsing something, it automatically goes down.

Monitor info keeps getting posted to syslog Ubuntu 18.04

Since my upgrade last week from 16.04 to 18.04 this keeps getting

"The system detected a problem, do you want to report it?" dialog

I'm getting this "The system detected a problem, do you want to report it?"
dialog. It does not say what the problem is. How do I find out what the
problem is? I am not interested in reporting it. I suspect it is something
stupid that I can fix, but I cannot figure out how to find out what is wrong.
This is with Ubuntu 14.04 LTS. I am used to CentOS and used to a less
pointy-clicky user interface, where one gets real error messages, not these
silly "idiot light" dianostics.

Menu System Tools/Software Updater not working after, Lubuntu upgrade from 16.04 to 18.04

Dear mailing list members, Colin,

When I run update-manager in the terminal there is no window popping up.

python3-numpy depending on *both* python 3.6 and 3.7

Hi,

while investigating some DEP8 failures currently in cosmic's
migration, I came across this:
$ dpkg -s python3-numpy|grep Depends
Depends: python3 (<< 3.8), python3 (>= 3.6~), python3.6:any,
python3.7:any, python3:any (>= 3.3.2-2~), libblas3 | libblas.so.3,
libc6 (>= 2.27), liblapack3 | liblapack.so.3

Is it ok/correct to depend on two python versions like that? Is the
point of it making sure numpy is available regardless which python 3
you are using?

mysql setup issue

I installed mysql on my new system (18.04). Ive followed the

to set the password.

sftp - can't figure it out!

I am baffled.

On an sftp server that I am setting up, the following is true:

I have a group "sftp_users".

I have a user "fred" whose primary group is "sftp_users". fred's shell
is /sbin/nologin.fred's home directory is /upload (the user will be
chrooted, see below).

In /etc/sshd_config I have these lines:

Subsystem sftp internal-sftp
Match Group sftp_users
   ChrootDirectory /mnt/efs/sftp/%u
   ForceCommand internal-sftp

Also, password authentication is disabled.

I have a directory /mnt/efs/sftp/fred. In that directory are two
subdirectories .ssh and upload.

How to install new Ubuntu without a CD

I have an old laptop that I keep running because it helps me with some
voluteer work I do. I want to install Ubuntu on it, but the way I'm used
to involved burning a CD or DVD, and its media reader no longer functions.
Is there a way to do this? It already has a somewhat old Ubuntu partition,
and I could use it, but the update process to make it current would be
laborious. I'd much rather have a fresh install.

Relationship between Release and Proposed repos for Cosmic

If I understand correctly, [1] suggests that the Cosmic (18.10) repos
have gnucash version 2.6.19 in 'Release' but 3.2 in 'Proposed'. Does
this mean that the intention is that 3.2 will be the version when
Cosmic is released?

Transition of LXD from deb to snap

Hello,

As some of you may know, we've slowly been pushing LXD users to use the
snap rather than the deb, whenever their environment allows it.

Starting with Ubuntu 18.10, we will be replacing the deb package
traditionally shipped in Ubuntu by the LXD snap.

There are a few pieces to that migration so I'll go into details about
each of them:

== Dependency management ==
LXD currently has the following reverse dependencies:

- adapt (depends)
- nova-compute-lxd (depends)
- autopkgtest (suggests)
- snapcraft (suggests)

We'll make sure that each of those are capable of handling the LXD sn

SOLVED: Problems with LTS upgrade -- to see if this is common

I'm not certain, and I'm unwilling to spend the day or so it would take to
verify, but it seems my difficulties had nothing to do with the general
upgrade process, but with my handling of GRUB itself. I may have had up to
3 different versions of GRUB involved: some early version, the 16.04
version and the 18.04 version. I never did a grub-install when I was
having the problems.

The problems went away when I did a grub-insall in front of every
update-grub (there were three points at which I did this).

Inplace Upgrade with Symbios RAID Controller

Hi,

I'm wondering if it is possible to upgrade in place from 16.04 LTS Server to 18.04 LTS Server.

As the server is somewhere in a rack i don't want to brick it by upgrading to Nirvana.

I would like to upgrade but I'm not sure if some software from outside the repo might be necessary.

Problems with LTS upgrade -- to see if this is common

I've got a small hoard of Ubuntu and Xubuntu machines in my garage doing
hobby stuff. One's a monster Xeon with 32 threads, 256GB RAM, RAID for all
but the boot partition and a fair amount of specialization. So I want to
be careful about the upgrade. Good thing I was, because it didn't go well.

So first thing I did was to boot a live DVD and copy the boot partition to
unallocated space on the same drive. There's plenty of room because the
real data is on the RAID volumes.

can't delete kernel

Hello all,

I tried to install a software package and was not allowed. It tried to
remove some old kernels and was unsuccessful and therefore would not
install the software. I tried the cli and synaptic with same results.
How can I again install software.

An observation (kernel 3.13.0-155 is broken WRT Java) and a Grub2 / Ubuntu question

OK, I just did updates at the local library, where the machines (except the
server's bare metal) run Ubuntu 14.04 LTS. The kernel update (3.13.0-155)
crashes (sort of) when you try to run a Java program (specificly the Arduino
IDE (1.8.5)).

My question is this: what is the "magic" to change the default kernel to boot?
With the grub2 configuration "magic" it is not a simple matter of changing one
line /boot/grub/grub.conf, but seems to require something far more arcane and
there does not seem to be a simple man page that explains this.

ubuntu-release-upgrader and postgresql

With the enabling of upgrades to Ubuntu 18.04 from Ubuntu 16.04 I've
been reminded of postgresql being in the blacklist of packages to

Bug 1787349[1] is a recent report of the upgrade being blocked because
of postgresql being in the blacklist and bug 871893[2] contains the
historical information on why it was added.

Trouble installing 18.04 server dual boot on laptop

Trying to duplicate the vm host server at work on my laptop. I’m having the following troubles:

The disk is partitioned using gpt partition tables and has a fresh install of windows 10 that created multiple partitions for windows use and left about 36gb or unused free space. I have since created 2 additional partitions in the remaining free space - an ext4 partition to be used as /, and a 16mb swap partition because the ubuntu installer insists that A swap partition exists but seems to care less about if it’s big enough to do a damn bit of good should it be needed.

HP printer not discovered

Thank you for reading this.

I normally use HP setup to discover my Ethernet connected printer,
however, my ISP has supplied me with a new modem and this is causing me

This may be due to existing firewall settings blocking the required

Requiring Launchpad 2FA from Ubuntu uploaders

Launchpad 2FA is currently opt-in for everyone. However, it has been
mandatory for Canonical employees for a number of years now. Details are
documented here:

<a href="https://help.ubuntu.com/community/SSO/FAQs/2FA" title="https://help.ubuntu.com/community/SSO/FAQs/2FA">https://help.ubuntu.com/community/SSO/FAQs/2FA</a>

TOTP and HOTP are supported, so this works with hardware authenticators
such as Yubikeys as well as smartphone apps like OTP Authenticator (from
F-Droid) and Google Authenticator (Play Store), etc.

We[1] think this is now easy enough and standard enough not to be a
burden, so we are inclined to implement this as a requirement for all
Ubuntu uploaders[2].

Static web photo gallery generator wanted

I'm looking for a simple, efficient way to generate an HTML gallery
from a hierarchy of jpeg images.

I.e. I have a directory ~/pictures which contains quite a deep
hierarchy of sub-directories oranising my pictures organised as I
want them. It's quite big, something like 30 thousand images which
total something over 50Gb.

I want a way to generate a web gallery with much smaller iamage files
(e.g. maximum image size something like 1024x1024) in a hierarchy
with simple HTML (or whatever) to make it navigable with a web
browser.

Warning from upgrages

For some time now, my upgrades have contained a warning that I do not
understand. It appears at the very end of the install process:

should do about it?

Upgrading over ssh and connection failure

I have several systems that I access via ssh. When I upgrade using apt
upgrade is there a danger of the upgrade seriously messing up if the
connection goes down in the middle of the operation, while upgrading the

like ending up with a non-bootable system.

Snap tutorial crashed my repositories

Hello 

I saw so much news from Ubuntu about snaps that I thought it was time I
learnt more.

So I found the tutorial on the website :

<a href="https://tutorials.ubuntu.com/tutorial/basic-snap-usage#1" title="https://tutorials.ubuntu.com/tutorial/basic-snap-usage#1">https://tutorials.ubuntu.com/tutorial/basic-snap-usage#1</a>

I am a retired Ubuntu end user so I tried just reading the steps first.
Then tried to install snapd. 41 packages were "no longer required" as
you will see from the clips of terminal messages below.
I don't know why apt could not connect to the network because I was
able to access other websites.

perl script prints parts of strings in the wrong order

hello,

I am trying to reuse an old perl script I wrote years ago, on an Ubuntu
16.-04LTS x86_64 box.
It behaves in a very odd way now, and I cannot figure out if it is the
code that is not
compatible with current versions of Perl, or if there is something VERY
strange happening
between the script, and the terminal it runs in.

The part of the script that works badly is this:

while (<INPUTFILE>) {
chomp;
my $LINE = $_;
many lines that "clean up" $LINE, removing certain substrings etc...

@F = split /:/, $LINE;
print "CURL:==> $F[0] ++ $CURLRES{$F[0]} ;;\n";
}

Proper way to handle britney hints

I would like to know how to properly handle updates to the so called
"britney hints", which controls how DEP8 test failures are handled in

It seems this communication got lost somehow.

Mplayer (and others too) occasionally pauses for no apparent reason

I run Xubuntu 16.04 and I like to play long, random selection music
play lists using mplayer.

Occasionally the sound just pauses for no apparent reason.

I have checked with top and htop, but there's nothing consuming a
significant piece of CPU time (i7, 8 cores, less than 1% on up to four
CPUs when this happens) or memory (less than 4GB out of 16GB in use).

I though t it might be Chrome, as I routinely have 4-8 tabs open, and
there are as many as 30 or more Chrome related entries showing in
htlop (I can't count them - too fast), but when exit Chrome, it still
happens.

I am running with my

stellarium problem

Using Ubuntu 16.04. Wanted to check out the location of close-by Mars
so installed stellarium via GUI but it won't run. All I get is an
instant flash of something on the screen. Htop does not see it running.
Locate gives me hundreds of stellarium-related files, so not sure what
to run via cli. This seems to be a snap install. Is there something
else needed to make it run correctly?

Not crucial - a phone app worked amazingly well, showing me what is in
the sky 'behind' the phone as I move the phone around in 3D space.

Trusty update broke libjansson

Hi,

We use the jansson library for parsing and generating JSON, and
today's update for Trusty appears to have broken the functionality to
lookup keys in JSON objects. This has severely impacted our services,
and we are having to try to find an old version and roll back to it.

Specifically, if you call json_object_get(), it fails to find keys that
are in the JSON object and returns NULL. We are loading the object via
json_load_file() first.

If there is more info you need or something else we should do, please let
me know.

The customer bug report arose because today, we are not handling all Ubuntu
