Public bug reported: I get unexpected symbol versioning errors on loading a WiFi module, both built-in and external:

My guess is that there is something quite weird going on with 'linux- modules-extra-6.8.0-22-generic' because compiling from source an out-of- kernel module should not have any such issues. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: kernel modules packaging -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2061684 Title: ULTS 24 linux 6.8.0-22 modules misversioned To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2061684/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
