Hello Thadeu, or anyone else affected,

Accepted v4l2loopback into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/v4l2loopback/0.10.0-1ubuntu1.2 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 for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

- linux-azure 5.0.0-1023.24~18.04.1
- linux-hwe-edge 5.3.0-19.20~18.04.2

The verification of the Stable Release Update for v4l2loopback has completed successfully and the package is now being released to -updates.
