Afraid to reboot

[Oderus]

Hi all. Just finished trying to upgrade to 19.04, and I got a LOT of errors, and I am afraid to reboot. Here is the entire log, errors occuring near the end. What should I do??

Looks like breakage caused by packages from unsupported 3rd party PPAs

In this case: https://launchpad.net/~fengestad/+archive/ubuntu/devel

Likely here that packages from that are incompatible with python from 19.04

Uninstall any packages installed from that PPA (force with dpkg if required), then do something like 'apt-get install -f' and 'apt-get dist-upgrade' to try to complete the install.

There are many messages, but the vast bulk are because python3 failed to on an install script. Looking for the specific error that is causing the failure, I found this:

Setting up python3 (3.7.3-1) ...

It looks like the Amiga emulator and the new Python are not getting along. The new Python is trying to update things in this application, and it can't, probably due to a bug similar to this one:
https://bugs.debian.org/cgi-bin/bugr...cgi?bug=914790

Now, in Ubuntu, the emulator is in the Universe part of the repos, which are mostly things automagically imported directly from Debian, and not packaged by Ubuntu proper, and are technically unsupported.

This is a good case for a bug report, as this is something that is easily overlooked, especially as it involves something that is not a commonly used application

So, fixing this should not be difficult.
First, see if you can uninstall fs-uae-launcher.
Next, run this command to re-run the package installs that didn't finish like so:

sudo dpkg --reconfigure -a

Then get a newer version of fs-uae-launcher from the PPA that the emulator's devs suggest:
https://launchpad.net/~fengestad/+ar..._filter=cosmic
This one is built specifically for Disco, so there should not be any issues.

In Ubuntu, this is fixed. No bug report required. The problem seems to be that they already had the 3rd party PPA packages installed, where the fix was not applied, with versions higher than the Ubuntu version number.

Then get a newer version of fs-uae-launcher from the PPA that the emulator's devs suggest:

This one is built specifically for Disco, so there should not be any issues.

It could still cause issues, as the maintainer of that PPA has not applied the fix that the Ubuntu archive package has!

thank you all for your input. I purged the ppa and performed the above mentioned commands, and everything works just fine. thank you so much! marking as solved.
