Is your username for this system actually 'username' or did you mask it when you posted the output? The issue is your software-center directory in the .cache directory is owned by root.
Try this command: sudo chown -R username:username ~/.cache Then try starting Software Centre. (Note the uppercase -R is important and also if your username is actually something else, replace it in the command) Let us know if this fixes your problem -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/725938 Title: Ubuntu Software center crashes when trying to open, but open successfully if tried to open via terminal. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
