Please unblock package netplan.io
I missed the hard freeze deadline by one day (after the 10 days soft
freeze delay). netplan.io is a key package, thus we need a manual
unblock.
Thanks.

[ Reason ]
A regression was found in upstream Netplan v0.106 (as uploaded into
testing via 0.106-1). It was fixed and merged upstream, incl. adding
additional integration tests (autopkgtests) covering this regression.
See: https://github.com/canonical/netplan/pull/331
[ Impact ]
If the fix is not applied/unblocked, Netplan's DBus Config() API will
be non-functional.
See: https://netplan.readthedocs.io/en/stable/netplan-dbus/
[ Tests ]
- We've added additional autopkgtests covering this regression
explicitly, which are passing in unstable:
* tests/integration/dbus.py
* tests/integration/regressions.py
- We've run snapd's "spread test" integration test suite, which
originally found the issue and confirmed it's now passing:
https://bugs.launchpad.net/netplan/+bug/1997467/comments/38
- We've run a manual test case:
$ busctl call io.netplan.Netplan /io/netplan/Netplan io.netplan.Netplan Config
$ busctl call io.netplan.Netplan /io/netplan/Netplan/config/XXX_CONFIG_ID io.netplan.Netplan.Config Set ss "network.bridges.br54.dhcp4=false" "90-test-config"
$ busctl call io.netplan.Netplan /io/netplan/Netplan/config/XXX_CONFIG_ID io.netplan.Netplan.Config Get
=> Make sure the io.netplan.Netplan.Config.Get() DBus call returns
some YAML output (not the empty string)!
[ Risks ]
- netplan.io is a key package, as a dependency of
debian-cloud-images-packages.
- The code fix is trivial: improve path building, by using
g_build_path() instead of g_strjoin() + propagating the correct
return value on failure.
[ Checklist ]
[x] all changes are documented in the d/changelog
[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in testing
