Thank you for taking the time to file a bug report. I set up a Focal LXD container and installed libsss-nss-idmap0 without problems in it. I see you tried to install version 2.2.3-3ubuntu0.2, and now in focal-updates we have 2.2.3-3ubuntu0.4, please try to install this newer version and check if your problem is fixed.
Since there is not enough information in your report to begin triage or to differentiate between a local configuration problem and a bug in Ubuntu, I am marking this bug as "Incomplete". We would be grateful if you would: provide a more complete description of the problem, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to "New". For local configuration issues, you can find assistance here: http://www.ubuntu.com/support/community ** Changed in: sssd (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1917280 Title: package libsss-nss-idmap0 2.2.3-3ubuntu0.2 failed to install/upgrade: dpkg-deb --control subprocess returned error exit status 2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sssd/+bug/1917280/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
