i've hit this problem before and found out i had not enabled the gcc5 repos ... well - my HDD crashed and i've had to reinstall Ubuntustudio (17.04) from scratch. I've done as I'm sure i did before, following these instructions: http://kxstudio.linuxaudio.org/Repositories but am unable to get guitarix plugins to work this time.
Preparing to unpack .../guitarix_2%3a0.35.6+git20170910v5_amd64.deb ...
Unpacking guitarix (2:0.35.6+git20170910v5) over (0.35.2-2) ...
dpkg: error processing archive /var/cache/apt/archives/guitarix_2%3a0.35.6+git20170910v5_amd64.deb (--unpack):
trying to overwrite '/usr/lib/libgxw.so.0.1', which is also in package libgxw0 0.35.2-2
dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)
Errors were encountered while processing:

Any help would be most appreciated, thanks
