Description: Ubuntu 23.10
Release: 23.10
$ apt-cache policy ubuntu-release-upgrader-core
ubuntu-release-upgrader-core:
Installed: 1:23.10.14
Candidate: 1:23.10.14
For completeness sake: I expected a system using Noble, but got a crash
instead ;-)
do-release-upgrade exits after printing "Calculating the changes" twice,
the last gasp was "=== Command terminated with exit status 1 (Sun May 26
22:24:00 2024) ===".
I'm attaching /var/log/dist-upgrade/screenlog.0
I ran strace -f on do-release-upgrade and found that it crashes in
/tmp/ubuntu-release-upgrader-cn6qkutf/noble which is a trivial Python
program. The cause is this:
Error in sys.excepthook:
Traceback (most recent call last):

Original exception was:
