I found myself in exactly this situation recently.

I had a machine running Beowulf with all mounted file systems as LVM logical
volumes. I created a duplicate LV of the root file system and rebooted from
it, then performed an upgrade to Chimaera.

I wasn't happy (for reasons that don't matter here) with the result, so I
simply re-booted back into the untouched Beowulf root FS.

Unfortunately I had neglected to consider the consequences of my having
created a separate /var partition in the first place, which got used by the
Chimaera upgrade, and was then thoroughly corrupted as far as Beowulf was
concered (mainly due to /var/dpkg, I'm sure).

It turned out that the "/usr/bin/apt-listchanges: not found" message is highly
misleading, and means that the script could not find the Python interpreter it
expected to, not that the script itself could not be found.

So, I think if you look at the first line of that script on your system, it
will point to something like /usr/bin/python3, which is probably a symlink to
something else in /usr/bin, which does not exist.

I hope this should at least give you some pointers as to what it is you need
to fix - get the correct version of Python3 installed.

Good luck,


Antony.
