For some reason, you still have Nvidia 550 driver installed, and that is causing the error. In Ubuntu 25.04, Nvidia 550 is a transitional package to newer versions.
I would purge out anything related to 550.xx driver and install 570 or 570-open driver. sudo apt purge *550* sudo dpkg --configure -a sudo apt install nvidia-driver-570-open ** Package changed: linux (Ubuntu) => nvidia-graphics-drivers-550 (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2115923 Title: package linux-headers-6.14.0-23-generic 6.14.0-23.23 failed to install/upgrade: installed linux-headers-6.14.0-23-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/nvidia-graphics-drivers-550/+bug/2115923/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
