Bug description:
[ Impact ]
With the current version of python3-defaults in jammy and noble,
packages which utilize py3compile and py3clean in their maintscripts
(which is more or less any package which includes Python modules), and
which also are affected by diversions installed by dpkg-divert, will
fail to install/upgrade/remove on systems with non-UTF-8 locales,
which include non-ASCII characters in their localized dpkg -L messages
(and which therefore produce output that is not valid UTF-8).
As this has the potential to break apt upgrade, the impact is quite
severe (especially if this occurs during a dist-upgrade). However, the
scope is probably *fairly* limited given this only affects systems
with non-UTF-8 locales (something that has not been the default for
many years), and which produce non-ASCII output (e.g. French
characters with diacriticals) in their localized messages for dpkg -L.
[ Rectification Plan ]
Firstly, python3-defaults must be patched in oracular, noble, and
jammy. doko has uploaded the fix upstream and synced this to oracular.
Benjamin has sponsored the noble and jammy SRUs.
Next, affected packages must be patched to include a "Breaks" line on
earlier versions of python3-minimal (the python3-defaults binary
package containing py3clean and py3compile).
Packages which install Python modules are easily selected, but those
affected by diversions are (computationally) impossible to select (see
comment 18 for details). Thus, determining the set of affected
packages was non-trivial, but Benjamin has kindly produced such a list
by empirical means (see comment 24). These will be added to the ticket
as they are uploaded.

remove_affected ISNULL) ORDER BY package;"

Code and resulting database can be found on

[ Test Plan ]
Where $series is jammy or noble as appropriate, and $package is the
name of the affected package being SRU'd:
$ lxc launch ubuntu:$series py3clean-test
$ lxc shell py3clean-test
# locale-gen fr_FR
Generating locales (this might take a while)...
fr_FR.ISO-8859-1... done
Generation complete.
# update-locale LANG=fr_FR
# exit
# adjust terminal to ISO-8859-1
$ lxc shell py3clean-test
# apt update && apt install --reinstall $package
With the current version of python3-defaults in jammy and noble this
should fail at the final apt install --reinstall step. With the
proposed version, it should succeed.
[ What Could Go Wrong? ]
The potential for regression is low since the python3-defaults changes
are minimal and have been reasonably tested, and the only change to
affected packages is the addition of a Breaks clause (i.e. the content
of the packages are unaffected, just the meta-data).
The major cause for concern is that we are not 100% certain that the
Breaks addition is sufficient to fix this. The Debian policy manual is
ambiguous as to whether Breaks implies that the fixed package must be
unpacked *before* the prerm maintscript of the package it breaks is
executed; the policy manual mentions this must happen before the
"unpack" phase, but prerm scripts run *before* the unpack phase.
However, in all experiments run so far, this did indeed resolve the
problem.
Still, as an extra hedge against failure here, we intend that the
python3-defaults SRU is released ASAP, and that we then delay a week
to allow it to propagate before releasing SRUs for the affected
packages.
[ Original Description ]
We noticed this in bug 2060769 but think it is a separate issue.
dh_python3 is putting a py3clean invocation into package prerm
maintainer scripts. When that runs, it explodes if the system
character set is for example ISO-8859-1.
This appears to affect every package for which dh_python3 has inserted
a call to py3clean into the package prerm.
python3-minimal 3.12.3-0ubuntu1
In this reproducer, cloud-init is at 24.1.3-0ubuntu3.3.
Steps to reproduce:
$ lxc launch ubuntu:noble rbasak-pro-l8n
$ lxc shell rbasak-pro-l8n
# locale-gen fr_FR
Generating locales (this might take a while)...
fr_FR.ISO-8859-1... done
Generation complete.
# update-locale LANG=fr_FR
# exit
# adjust terminal to ISO-8859-1
$ lxc shell rbasak-pro-l8n
# apt update && apt install --reinstall cloud-init
