I've attempted to:
"To use it edit the /etc/apt/sources.list file on your system and add the
line:
deb http://jxself.org/repo/freesh/ freesh main
You should also fetch and install the GPG key with which the repository is
signed, with the commands:
wget http://jxself.org/repo/freesh/archive-key.asc
sudo apt-key add archive-key.asc "
but it won't let me update the sources.list file. I thought I was logged in
with root privileges? Is there a way I don't have root access? This is my
machine, and I entered my password upon login. . .
