I changed my password then chnaged it back again. Now I cant get back into my user adnin message...could not update ICEauthority file/home/username/.ICEauthority This has probably been covered can somone point
I have solved this. The problem was with 11.10 in some way. I had given up, so I put the 12.04 CD in to start the new installation. Well I thought that I would just try the proceedure 1 more time.
Well with the 12.04 live CD it all went correctly and offered me the chance to use my mount passphrase at last. And I just copied the home directory into my w7 partition while I re-installed. So the lesson is use the 12.04 live cd even if you are running 11.10 etc. Alls well that ends well.
Maybe that file has wrong permissions or belongs to another user. Check that it belongs to your user and has only read and write permissions to that user:
If something is wrong you can fix it with those commands, then logout and login again:
Hope this helps.
