Okay, after some digging I managed to make it run. The problem was just that the kernel source couldn't be located despite having it already in /usr/src
by unpacking the content of kernel-source-5.4.0.tar.bz2 to a fake linux- headers-5.4.0-1018 directory and copying extra config files etc from the original linux-headers Hopefully someone will fix this? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1895470 Title: fatal error: classmap.h: No such file or directory To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-kernel-headers/+bug/1895470/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
