Hello Morozov, I'm sorry but the build is failing in a 3rd-party dkms driver that Ubuntu doesn't natively support. I'm afraid we cannot assist you in debugging this failure.
The problem seems to be that your kernel (version 6.8.0-52-generic) has been updated such that the rtl8821CU driver (version 5.4.1) no longer matches what is required for it to build. Please contact your device's vendor, Realtek, to see whether they offer a software update for the 6.8 kernel. ** Changed in: linux (Ubuntu) Status: New => Won't Fix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2097754 Title: package linux-headers-6.8.0-52-generic 6.8.0-52.53 failed to install/upgrade: installed linux-headers-6.8.0-52-generic package post-installation script subprocess returned error exit status 11 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2097754/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
