[Bug 1990326] Re: ubuntu server 20.04.5 cannot be installed after enable secure boot

[Timo Aaltonen]

Hello shangsong, or anyone else affected,

Accepted debian-installer into focal-proposed. The package will build
now and be available at https://launchpad.net/ubuntu/+source/debian-
installer/20101020ubuntu614.4 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-
focal to verification-done-focal. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-focal. 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.

** Changed in: debian-installer (Ubuntu Focal)
       Status: Confirmed => Fix Committed

** Tags added: verification-needed verification-needed-focal
