Hello Balint, or anyone else affected,

Accepted unattended-upgrades into xenial-proposed. The package will
build now and be available at https://launchpad.net/ubuntu/+source

in the -proposed repository.

Please help us by testing this new package.  See

to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-xenial to verification-done-xenial. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-xenial. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in

N.B. The updated package will be released to -updates after the bug(s)
