** Description changed:
[Impact]
Users with a python pip installation of distro-info are not able to upgrade
from Ubuntu 18.04 LTS to Ubuntu 20.04 LTS because the pip version of
distro-info does not contain information which the Ubuntu version of the
package does. More generally, locally installed python packages can interfere
with the release upgrade process due to how the process is started.
[Test Case]
- The pip version of distro-info which is available Ubuntu 20.04 LTS does not
have this problem or is not installable as the distro-info package is a greater
version, so this isn't testable there however a regression test should be fine.
+ The pip version of distro-info which is available Ubuntu 20.04 LTS is not
installable as the distro-info package is a greater version, however one can
workaround this by manually removing python3-distro-info (sudo dpkg -r
--force-depends python3-distro-info), pip3 install distro-info, and then
reinstalling python3-distro-info.
1) on an Ubuntu 18.04 LTS system install pip
2) pip install distro-info
3) Run do-release-upgrade
4) Observe a crash with a Traceback re distro-info and get_all
- With the versin of the release-upgrader from -proposed you will not
+ With the version of the release-upgrader from -proposed you will not
experience such a crash.
[Regression Potential]
The change is to start python3 with "-s" which will not add the user side
directorty to sys.path. This is a safe change but we should still ensure that
upgrades succesfully complete to the next release of Ubuntu. Which should also
check and ensure that all packages and snaps are updated.
