The update to 13.04 was offered, I accepted but it failed. Now neither Software Centre nor Updater will open. SC opens for a second then closes; Updater tells me:
Failed to load the package list This is a serious problem. Try again later. If this problem appears again, please report an error to the developers. E:The package defoma needs to be reinstalled, but I can't find an archive for it.
This isn't the first time I have had problems with software sources on 12.10. Both my desktop and laptop stopped getting updates and I resolved the issue by following solutions online involving cleaning and updating the package lists. I have followed various solutions this time but without success.
I am currently downloading the ISO for 13.04. Can I update with this or can it only be used for a clean install? I would rather upgrade and keep my apps.
