first of all thanks for all the good work you're doing.
i can easly install packages from your backport but i'm having problem with the public key.
this is the output from wget -O -
http://backports.org/debian/archive.key | apt-key add -
gpg: can't open `/etc/apt/trusted.gpg'
gpg: keydb_get_keyblock failed: eof
gpg: no writable keyring found: eof
gpg: error reading `-': general error
gpg: import from `-' failed: general error
how can i resolve this?
