An upload of ovn to jammy-proposed has been rejected from the upload queue for the following reason: "Unnecessary packaging changes in the disable-these-tests infrastructure. If you think they are necessary, please ping RAOF on #ubuntu-release and I can accept from the rejected queue.".

Hello Frode, or anyone else affected,

Accepted ovn into jammy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/ovn/22.03.2-0ubuntu0.22.04.1 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, what testing has been performed on the package and change the tag from verification-needed-jammy to verification-done-jammy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-jammy. 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 for helping!
