After update to version 12.04 the Update Manager crashes all time. In addition Firefox have lost most plugins, and its impossible install these it seems (no error, but plugins are still missing after installing). Even LibeOffice is changed. All icons are gone so its a text version now ("Summarize" in stead of icon for this "sigma-sy,bol").
Can I reset to older versions? Other suggestions?
In worst case I have to remove Linux and go back to Windows. :(
