** Description changed:
[Impact]
It is not possible to use "Repair broken packages" in friendly recovery as it
calls dist-upgrade.py and that fails as it checks to see if the python symlink,
not python3 symlink is good.
[Test Case]
Run the following as root:
env RELEASE_UPGRADER_NO_SCREEN=1 python3 "/usr/lib/python3/dist-
packages/DistUpgrade/dist-upgrade.py" --partial --frontend
DistUpgradeViewText --datadir /usr/share/ubuntu-release-upgrader
With the version in the archive you'll receive an error regarding your
python install being corrupted, with the version from --proposed you
won't.
+
+ Also after installing the new version of python3-distupgrade the system
+ should be booted into recovery mode and it confirmed that the "Repair
+ broken packages" menu item works.
[Regression Potential]
The code is just being updated to use python3 instead of python so there
isn't any change of a regression.
The menu item "Repair broken packages" calls the following command:
env RELEASE_UPGRADER_NO_SCREEN=1 python3 "/usr/lib/python3/dist-
packages/DistUpgrade/dist-upgrade.py" --partial --frontend
DistUpgradeViewText --datadir /usr/share/ubuntu-release-upgrader
However, that fails with the following:
Your python install is corrupted. Please fix the '/usr/bin/python'
symlink.
This is because of the _pythonSymlinkCheck function in
DistUpgradeController.py (provided by ubuntu-release-upgrader) using
os.readlink('/usr/bin/python') but not os.readlink() on what the first
os.readlink() call returned. That being said the whole function should
be updated to see if python3 is being used.
