I basically worked on two cases:

# ulfius autopkgtest fail

The ulfius autopkgtest were failing on all the archs. After 
investigating (thanks Christian for the help there) the issue turned out 
to be with IPv6 testing: the autopkgtest testbed set the http_proxy env 
variable but doesn't add ::1 to no_proxy. I filed LP: #1945634 about it, 
hoping for a simple fix on the autopkgtest infra, but it turns out it 
isn't really simple (LP: #1908136).

In any case the bug can serve as a reference bug for packages affected 
by the same issue. I left the update-excuse tag so when bug tasks are 
added it will show up in update_excuses.

I patched the ulfius autopkgtest (debdiff attached to the bug); the 
patch is simple and should easily apply to other cases.

ulfius 2.7.1-3ubuntu1 migrated.

# mpv autopkgtest fail

mpv 0.33.1-1ubuntu1 was regressing the python-mpv autopkgtests on 
ppc64el. I identified this as a race condition in the upstream test 
suite, where an arbitrary sleep() is present. I filed an upstream issue 
and PR [1,2], and applied the patch as an Ubuntu delta for now.

Before uploading the package the fix was tested on the actual 
autopkgtest infra using a "testing against a PPA" trigger [3].

mpv 0.33.1-1ubuntu1 migrated.

# Tooling work

For $reasons I recently converted /var/lib/schroot to ZFS, but the naive 
approach (create dataset && copy stuff over && rename) didn't work as 
ZFS doesn't support overlay mounts (LP: #1718761), so my type=directory 
schroots didn't work anymore.

I wanted to recreate them as type=zfs-snapshot schroots, so I patched 
mk-sbuild to add support for them:

https://code.launchpad.net/~paride/ubuntu-dev-tools/+git/ubuntu-dev-tools/+merge/409346

(currently in Needs Review state). Once I get review/feedback on this 
I'll add something similar to sbuild-launchpad-chroot.
