Red Ribbon GNU/Linux is based on Debian and uses it’s repositories to provides the most of the packages to install the applications.
Debian has dropped the support for PowerPC BE (the platform on which the PS3 is based) and has archived the Jessie repositories, but don’t worry, I’m working to solve this inconvenience.
For now, in order to continue using the Debian Jessie repositories, it is necessary to update the sources.list directory and change the lines “ftp.debian.org” to “archive.debian.org”.
To apply the fix, you can edit the sources.list file manually or open a lxterminal and download the file:
Then, you can execute it:
sudo sh online-fix-2019-06-05.sh
