Just in case anyone finds this by searching, and can't figure out how to fix it:
Simply run: $ sudo apt-get remove igt-gpu-tools intel-gpu-tools $ sudo apt-get install intel-gpu-tools (Use `apt` in place of `apt-get`, if you prefer; syntax is the same.) During the remove phase, APT will finish the remaining install actions which had been broken by the igt-gpu-tools package bug. So output will likely be longer than expected. After that, the install will succeed. This is purely a bug of 'new version trips over old version', and will not happen if the old version is first cleared away. Optional: install 'igt-gpu-tools' instead of 'intel-gpu-tools', since it looks like the latter is now an unneeded, empty stub (all it does is install 'igt-gpu-tools'). Cheers, >Bela<
