[impact]
ebtables cannot be upgraded on Ubuntu 18.04 for WSL.
[test case]
on a WSL installation that already has ebtables installed (most
installations do), try to upgrade the package with apt or dpkg; its
prerm script will fail, and prevent the upgrade.
+
+ The easiest way of triggering the problem is reinstalling the package:
+ $ sudo apt install --reinstall ebtables
[regression potential]
the ebtables init script is changed to never return an error code when
called as 'stop', so anything that depends on the script returning an
error code when 'stop' fails will no longer work correctly. However,
nothing appears to use the 'stop' return value, besides the package's
prerm script, which is what is causing the upgrade failure.
Additionally, the prerm script is updated to ignore 'failed-upgrade'
failures, to allow upgrading over the previous version(s).
Finally note that the rpm-specific ebtables.spec file that is included
in the package specifically ignores the 'stop' return value, i.e.:
- /sbin/service ebtables stop &>/dev/null || :
+ /sbin/service ebtables stop &>/dev/null || :
[other info]
note that ebtables is effectively dead upstream, so it's extremely
unlikely there will be many more package updates/srus, except to fix
minor bugs such as this.
