Re: Problems with 13.04
gksudo "update-manager -d" is not for ordinary updates, it should only be used if you want to upgrade to the development version of Ubuntu.

As for Thunderbird, it is asking for your password because it's getting no reply or an invalid reply from the mail server (usually at your ISP). Thunderbird's default setting is to guess what method of authentication your ISP uses. Sometimes it gets it wrong and you have to specify it manually in the Thunderbird settings; try a few different authentication types and see what works.
Sometimes, your ISP will do upgrades on the mail server that will cause Thunderbird to be confused about what authentication type is correct. Maybe your ISP has changed authentication type completely, and only checked that Outlook Express gets it right. If you've just done the upgrade to 13.04, it's even possible that your ISP's mail server is down for maintenance; your exact problem used to happen to a friend of mine, whenever their ISP's mail servers crashed. Thunderbird can't tell the difference between "bad authentication" and "No authentication because your ISP is having problems", so it assumes you've got the password wrong and asks for the password again. Evolution does the same, and so does Network Manager when you're using wifi.
I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.
