[Bug 1786491] Re: grub2 verify signed kernel exists or abort upgrade

[Łukasz Zemczak]

Hello Julian, or anyone else affected,

Accepted grub2 into bionic-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/grub2/2.02-2ubuntu8.3
in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
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-bionic to verification-done-bionic. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-bionic. 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
advance!
