Description

The following description is copied from the attached file, which also contains the full Tails Server log:

# 1. I started the Tails Sesrver GUI and told it to install Prosody
#    before Tor had bootstrapped so it showed the expected "Tor has
#    not bootstrapped error" 
# 2. Tor actually seemed to have got stuck, so I restarted it
# 3. Tails Server immediately picked up when Tor had bootstrapped and
#    started to install prosody
# 4. However, it got stuck on the "Installing" status, but I did check
#    and prosody *had* been installed
# 5. At some point I tried to remove the stalled Prosody service from
#    Tails Server, and I think that's why the exceptions where thrown
#    below. I believe I clicked the remove button twice, which would
#    explain the *two* identical exceptions.
#
# So here the real issue is 4 -- Tails Server shouldn't ever get stuck
# here. But I also find 5 ugly, that I cannot remove a service that's
# in a broken half-installed state and must solve it by restarting
# Tails Server.

It seems like the apt-get install never returned, because the next line in TailsService.install() would have logged 'prosody' installed, which is not in the log.
What did you check to come to the conclusion that Prosody had been installed? Note that we don't uninstall the APT packages during the service uninstallation.

dpkg -l prosody listed a version. I am quite sure I did not look at the first column and make sure it was ii, so perhaps the package wasn't properly installed (e.g. a post install hook failed) and this confused Tails Server?

Note that we don't uninstall the APT packages during the service uninstallation.

I know; did I contradict this, some how?

This is possible.

No, sorry, I had a thought that didn't make sense.

I don't think we can figure this out until someone experiences this again and can look at the logs.

It just happened to me again (this time Tor was bootstrapped, so that part of my original report seems orthogonal) and ...

... unfortinately I only had info level logs since that is the new default. I'll make sure to always start tails-server with --verbose from now on.

The info level is not a new default, it's always been the default. But there is also always the /var/log/tails-server.log with debug level messages.

But I guess the Tails Server log would not be of much help, because we already have a log of an occurrance of this bug. According to this log, the apt-get call didn't return, so I guess the APT log would be more interesting (and checking if the apt-get process is still running).
