    Yesterday I experienced the same problem with the bg. mirror on my 2 computers with Ubuntu. I tried to open http://bg.archive.ubuntu.com from the browser and received an error. Then I tried http://archive.ubuntu.com and I saw it's working.

    So the solution was temporary switching from the local repository bg.archive.ubuntu.com to the central repository archive.ubuntu.com by editing of the file /etc/apt/sources.list. You can do this from the command line by using sed command in this way:

    sudo sed 's/bg.archive.ubuntu.com/archive.ubuntu.com/g' /etc/apt/sources.list -i.bak

    Later you can restore the original state by the command:

    sudo mv /etc/apt/sources.list.bak /etc/apt/sources.list

  2. I have gotten that problem before and it was the Firewall/Content Filtering appliance that was blocking access to some of my repo addresses. Not sure if that is a possibility for you.

    I whitelisted my linux host on the Firewall/Content Filtering appliance so that it would have unrestricted access outbound.
