OK. You have to uninstall libcompshad -- this package was for Hardy, and it is obsoleted by libcompshad3. Only *after* uninstalling it you will be able to install libcompshad3.
As for nxagent... I am sorry, not supported. If you have an issue with it, you will have to contact the PPA authors. Finally, I would like to stress the dangers of mixing packages from different versions, but I think the point is already made ;-) you might consider publishing (on the forum) the current steps to install nx as a help to others. I am, now, closing INVALID this bug (as NOTABUG, actually). Please do not hesitate in reopening it if you do not agree with my action, or to open any new bugs you may find. ** Changed in: nxcompshad (Ubuntu) Status: Incomplete => Invalid -- trying "sudo apt-get install nxagent" package libxcompshad3 not installed failed to install/upgrade: trying to overwrite /usr/lib/libXcompshad.so.3 , which is also in package libxcompshad 0:3.2.0-1hardy1 https://bugs.launchpad.net/bugs/480339 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
