[Bug 2080204] Re: unable to upgrade to ubuntu 24.04 from ubuntu 22.04

[LucMorizur]

(Still trying to go forward, hoping I'm not overpassing some posting
policy)

I removed all files from /etc/apt/sources.list.d/ folder, so to remove
all PPA's from the system, and proceeded to an apt update after that.
Then I tried once more a release upgrade, and I got an error message at
the same step than the other times, but now the message was slightly
different (still Google translated from French):

Unable to evaluate upgrade

An unresolvable problem occurred while calculating the
upgrade. If none of these apply,
report this bug using the command "ubuntu-
bug ubuntu-release-upgrader-core" in a terminal.
If you want to analyze the problem yourself,
the log files in the "/var/log/dist-upgrade" directory contain
the information about the upgrade. Specifically, please see the
"main.log" and "apt.log" logs.

It does not mention any more that the error « was probably caused by: * unofficial software packages that
did not come from Ubuntu », and to « use the "ppa-purge" command ».

It thus suggests that the issue is actually not caused by some PPA
issue.

Unless I was wrong by just moving files out from
/etc/apt/sources.list.d/ folder so to remove PPA's...
