regression on bionic

[Anthony Godshall]

An install via apt in ubuntu 16.04 xenial works
fine, but an install on 18.04 bionic (specifically,
ubuntu-mate) fails to produce a working system.

Logs report missing guacamole.war file.

Downloading the packages from xenial and installing
them produces a working system, to wit:

dpkg -i \
  libpng12-0_1.2.54-1ubuntu1.1_amd64.deb\
  libguac5_0.8.3-2_amd64.deb \
  libguac-client-ssh0_0.8.3-2_amd64.deb\
  libguac-client-vnc0_0.8.3-2_amd64.deb\
  guacamole_0.8.3-1.2_all.deb \
  guacd_0.8.3-2_amd64.deb \
  guacamole-tomcat_0.8.3-1.2_all.deb

[Anthony Godshall (agodshall)]

OK, this bug report is about gaucamole, guacd, and guacamole-tomcat.

I don't understand why it still says guacamole-client above-
I saw that previously and carefully navigated to guacamole-tomcat,
which routed me to guacamole, and I accepted that.

Clearly there is something I'm not groking about launchpad and
ubuntu bug reporting : - (

Thanks for taking your time to report this issue and help making Ubuntu better.

>I don't understand why it still says guacamole-client above

There's two parts to this answer. The first is that multiple binary packages (which we install) might be built from the same source package. Launchpad tracks source packages, so any bug reported towards a binary package will be filed under the source package it came from. In this case, the source package is named guacamole-client, and one (they only) binary built from it is guacamole (https://launchpad.net/ubuntu/+source/guacamole-client/0.9.9+dfsg-1).

The second part is that a while back the guacamole and guacamole-tomact packages were merged together, seee https://launchpad.net/ubuntu/+source/guacamole-client/+changelog

I'm somewhat curious why your listing seems to still include the guacamole-tomcat package and being version 0.8.3-1.2, when the bionic repositories offer 0.9.9+dfsg-1. Looks like you might have some of the older package versions which might be causing issues.

Could you please run the following command (only once) in a terminal to gather additional debug information:
apport-collect 1806510

When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. This will automatically version numbers and which Ubuntu release you are running, among other things. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

Apparently I wasn't clear.

installing 0.9.9 (the version in ubuntu-mate 18.04 bionic repos)
failed as described.

installing 0.8.3 is the workaround from 16.04 repos is the workaround.

OK, will try to do that. I didn't think to report the bug till I had
found the workaround, and now that I have rolled back the packages to
functional, I'm loath to break it again.

what I meant to say is:

installing 0.8.3 from the 16.04 repos is the workaround.

Could you add some more details on where you found the log message on missing guacamole.war?

I tried installing guacamole on my 18.04 system to check if I got the same error message, but didn't find a binary file so I'm a bit stumped on how to reproduce this issue.

[Andrey de Oliveira (crazy2010)]

Hello,

I had the same problem here installing guacamole package on a clean install of Ubuntu 18.04 LTS via apt install guacamole.

Apparently the problem occurs because two required packages are not as dependencies and the post-run scripts are not creating some essential symbolic links

Correction:
Install libactivation-java and libstax-java packages that in my understanding should be as dependency:

apt install guacamole libactivation-java libstax-java

Create the symbolic links below:

ln -s ../../../../java/javax.activation-1.2.0.jar /usr/share/guacamole/guacamole/WEB-INF/lib/javax.activation-1.2.0.jar
ln -s ../../../../java/jaxb-core.jar /usr/share/guacamole/guacamole/WEB-INF/lib/jaxb-core.jar
ln -s ../../../../java/jaxb-api.jar /usr/share/guacamole/guacamole/WEB-INF/lib/jaxb-api.jar

Restart tomcat8
systemctl restart tomcat8

That's all, folks.

[Hans Joachim Desserud (hjd)]

Marking as confirmed since others experience the same issue.

[Andrey de Oliveira (crazy2010)]

A correction to my previous post:

Instead of creating this link:

ln -s ../../../../java/javax.activation-1.2.0.jar /usr/share/guacamole/guacamole/WEB-INF/lib/javax.activation-1.2.0.jar

Create the link this way:

ln -s ../../../../java/javax.activation.jar /usr/share/guacamole/guacamole/WEB-INF/lib/javax.activation.jar

Hi Hans.

I'm going to guess it was /var/log/syslog, but I don't have my notes.

That appears to be where it logs by default, and I don't recall having
changed that.

Hi again Hans.

Also look in /var/log/tomcat8/catalina.out maybe

Thanks Andrey.

DDs and UDs: would /var/lib/dpkg/info/guacamole.postinst be the right
place for those commands?

Hi Anthony Godshall,

These commands are a workaround for the currently available package.

In my opinion, for the definitive fix, the symbolic links should already be contained within the package, in the same way as the others are already.

Look in /var/lib/dpkg/info/guacamole.list for the list of files already in the package. All files is /usr/share/guacamole/guacamole/WEB-INF/lib/ are symbolic links.

In addition to these symbolic links, the package must also require the dependencies that are missing.

adding this:
