HD Install :: /tmp/authority error
yeah now fixed everything works now it's to do with using the gui
The problem that you experienced is due to one of your *.dsl extensions being built wrong (I don't know who the "bad apple" is).
Basically, what happens is the bad *.dsl file changes the permissions of the /tmp folder and you are no longer allowed to write to it unless you are running as user 'root'.
A quick way to check for this problem is to type this:
tar -ztvf filename.dsl | more
Then look for the following entry in the list:
/tmp/
or
/var/tmp/
If you see this entry, then your dsl file may cause you some trouble.
Hope this helps.
yeah thanks again, and now i know how to resolve it should this happen again. I greatly appreciate your help being a total linux newbie just 6 weeks or so but am trying to soak up what i can.The amount of stuff I have learned from this forum is remarkable KUDOS
