Hi @dfouch, appreciate you reaching out!
I am on the engineering team; we haven't seen this issue yet but it's likely due to our team updating the builder images which are linked to a later version of glibc. It looks like at the moment, RHEL 8 (and CentOS Stream 8 ) only support up to glibc-2.28. RHEL 9+ support glibc-2.34+ (if the data on distrowatch is correct).
At the moment, downgrading duoconnect to v2.0.4 (link: https://dl.duosecurity.com/DuoConnect-2.0.4.tar.gz) should unblock your system and ignore the update that the Duo Network Gateway advises when connecting to an SSH server.
We are going to internally investigate if we can remove the dependency on glibc for DuoConnect on Linux. If we are able to successfully remove the dependency, we can provide a preview 2.0.8 release for you to test. Would that be helpful? We will begin investigation today and hope to have more information early next week!
We'll also make a note on our release notes page about this glibc deprecation as well.
