In trying to recreate the issue this afternoon, it looks as though installs based on all of the updated / most recent packages are succeeding again (i.e., this may no longer be an issue).
In our dpkg logs, we noticed that an update came through today for libc- bin (2.27-3ubuntu1), and wonder if this update may have been part of what resolved the issue. If that is not part of why this is working, then I will bury my head / beg your forgiveness and try to figure out if there was some other cause. Please understand that this stopped working the same day that we got the libsasl2 package updates, and that reverting the libsasl2 updates allowed us to get our installs working, so that is why we filed a bug against this package. Thanks again for your help. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1861230 Title: _sasl_plugin_load failed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cyrus-sasl2/+bug/1861230/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
