Bug#921383: zfs-linux: autopkgtest is broken with two linux versions in apt's cache

[Paul Gevers]

Source: zfs-linux
Version: 0.7.12-2
X-Debbugs-CC: debian-ci at lists.debian.org, perl at packages.debian.org
Severity: important
User: debian-ci at lists.debian.org
Usertags: issue

Dear maintainers,

You package has an autopkgtest, great. However, while debugging a
regression in your package, seemingly caused by perl, ntyni on
#debian-perl spotted an issue in your autopkgtest
(https://salsa.debian.org/zfsonlinux-team/zfs/blob/master/debian/tests/dkms-zfs-test#L4).
You're not handling the case where there are two linux versions in the
cache of apt (as will often be the case when running autopkgtests in the
migration context of ci.debian.net). I copied some of the output at the
bottom of this report.

Currently this regression is blocking the migration of perl to testing
[1]. To avoid perl from being stuck behind linux (which is blocked) I'll
have the migration software ignore the failure of you package until this
bug is fixed.

More information about this bug and the reason for filing it can be found on
https://wiki.debian.org/ContinuousIntegration/RegressionEmailInformation
