Upgrading to Ubuntu 10.04 Behind a Proxy
If you do a update-manager -d
under Ubuntu 9.10 and happen to be behind a firewall, you might notice that it appears to freeze as soon as you click on the Upgrade button. This is caused by a known bug in Ubuntu where the start of the upgrade process doesn't take your proxy settings into account.
It's been fixed in 10.04, but that doesn't help you if you're using 9.10 or 9.04.
So how do you fix it?
