After some week i trie to play Planeshift again and client and setup still work.
But as i'm trying the use the upgrader he want not start.
After i have started upgrader in terminal to see what is going on.
Upgrader seems habe been upgraded at last upgrade and is using a new lib (libxaw.so.8 )now, who does not exist in my release (Ubuntu Dappe lts 6.06) cause this lib is still under develloppent and not stable.
While upgrade the upgrader the new lib you are using ,has not bee downloaded in library folder of Planeshift . Only libxaw.so.7 is in there .
I think client and setup is still using release 7 of libxaw.
But if you try to make some file upgrade of Planeshift in next futur days lot of linux player will be again unable to play Planshift.
