I can't install Ubuntu because of UEFI. So, I'm using vm-ware. Sadly, it runs slow on newer versions of Ubuntu. 11.04 & 10.04 run great.
Problem is: I can't use the software center. I tried replacing "ubuntu.com" with "old-releases.ubuntu.com" in
Nothing. I run
sudo apt-get update. This is what I get: http://pastebin.com/jLRf3MwG
I would install everything manually, but most of the software I use provide installation through Ubuntu repositories only.
