The package will build now and be available at https://launchpad.net/ubuntu/+source/glibc/2.31-0ubuntu9.5 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. ** Tags removed: verification-done verification-done-focal ** Tags added: verification-needed verification-needed-focal -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1918035 Title: ld-2.31.so is not correctly packaged in libc6-dbg To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/1918035/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi, thanks for reporting and for fixing this! Unfortunately, I'm on Ubuntu 21.04 where the fix hasn't arrived yet as we're still on 2.33-0ubuntu5 [1], and I was wondering if it could be possible to release at least the update to 2.33-0ubuntu6 in there as well, so that we can have sane stack traces again without waiting for the 21.10 release (which I see already have 2.33-0ubuntu9 [2]). WDYT? Would that be possible? Thanks in advance!
