Hi Ubuntu forums, it's me again.
After a clean, fresh install of Lubuntu 13.04 32 bit on an offline machine, I am desperately trying to update and upgrade all the packages with the help of an online computer.
The program of choice was apt-offline and when entering the last command to install the packages:
I get the error:
sudo apt-offline install --verbose apt-offline.zip
So I thought this would be a bug with apt-offline, but the developer found out that this is a bug with the extra repositories for Ubuntu. Read about it here.
ERROR: I couldn't understand file type extras.ubuntu.com_ubuntu_dists_raring_Release.gpg
Please help, as I am not able to solve this by myself.
