[Bug 2038949] Re: do-release-upgrade fails because dependencies cannot be satisfied

[Nick Rosbrook]

That's actually not what's causing the upgrade to fail. While there is
something wrong with "c..archive.ubuntu.com", the upgrader will just
just "arhive.ubuntu.com instead. E.g., from
VarLogDistupgradeMainlog.txt:

The real error, seen in VarLogDistupgradeAptlog.txt, is this:

Normally these sort of things with python are caused by using the python
deadsnakes PPA. I am not sure about the other package at the moment,
though.

** Summary changed:

- do-release-upgrade makes incorrect changes to sources.list, causing crash
+ do-release-upgrade fails because dependencies cannot be satisfied
