** Description changed: + [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. + + [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 || : + + [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. + + [original description] + ebtables cannot be upgraded on Ubuntu 18.04 for WSL. apt-get upgrade fails with the following error: Reading package lists...
