So the Support Legacyheader was a red herring. Debugging the ubuntu-drivers python showed that ubuntu-drivers install calls the following: apt-get install -o DPkg::options::=--force-confnew -y nvidia-driver-460 linux-modules-nvidia-460-generic
when run manually this gives the output: Preparing to unpack .../libnvidia-gl-460_460.84-0ubuntu0.21.04.1_amd64.deb ... diversion of /usr/lib/x86_64-linux-gnu/libGL.so.1 to /usr/lib/x86_64-linux-gnu/libGL.so.1.distrib by nvidia-340 dpkg-divert: error: mismatch on package when removing 'diversion of /usr/lib/x86_64-linux-gnu/libGL.so.1 by libnvidia-gl-460' found 'diversion of /usr/lib/x86_64-linux-gnu/libGL.so.1 to /usr/lib/x86_64-linux-gnu/libGL.so.1.distrib by nvidia-340' dpkg: error processing archive /var/cache/apt/archives/libnvidia-gl-460_460.84-0ubuntu0.21.04.1_amd64.deb (--unpack): new libnvidia-gl-460:amd64 package pre-installation script subprocess returned error exit status 2 Selecting previously unselected package libnvidia-ifr1-460:amd64.

Searching for this error led me to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics- drivers-390/+bug/1768050 where the suggested fix for running dpkg-divert --remove, resulted in ubuntu-drivers install running successfully. Not sure why this output didn't show up when I initially call ubuntu- drivers from the cmd line. Perhaps because the GUI had already called it and now apt was unhappy there was no output, just a non-zero return code? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to ubuntu-drivers-common in Ubuntu. https://bugs.launchpad.net/bugs/1934882 Title: package has invalid Support Legacyheader Status in ubuntu-drivers-common package in Ubuntu: New Bug description: Having recently upgraded 20.10 -> 21.04 it is no longer possible to install the nvidia drivers.
