According to mintsources.conf there are
default=http://packages.linuxmint.com
base_default=http://archive.ubuntu.com/ubuntu
mirrors=/usr/share/mint-mirrors/linuxmint.list
base_mirrors=/usr/share/python-apt/templates/Ubuntu.mirrors
could the change of base_mirrors (Ubuntu) please also be included? At the moment the script only selects a Mint-Mirror.
Will it be possible to add a simple command line switch to revert official-package-repositories.list back to default and base_default?
