Changing source for packages: lines in sources.list apt.conf.d 00knoppix
I wish to change the defaultsource for Synaptic. I changed the line in:
Code:
/etc/apt/apt.conf.d/00knoppix
From:
Code:
APT::Default-Release "wheezy";
To:
Code:
APT::Default-Release "squeeze-backports";
and
Code:
/etc/apt/sources.list
From:
Code:
deb http://ftp.de.debian.org/debian stable main contrib non-free
and other lines To:
Code:
deb http://ftp.de.debian.org/debian-backports/ squeeze-backports main non-free
The original files have been renamed and kept, and can be restored.
Synaptic gives this error message
Code:
E: The value 'squeeze-backports' is invalid for APT::Default-Release as such a release is not available in the sources
E: _cache->open() failed, please report.
and closes.
What more needs to be done?
The change is required to clean reinstall nvidia drivers and repair the following error codes as Output: Synaptic_Changes_Applied_terminal.txt
For nvidia drivers the following errors are known to the system:
Code:
ERROR: The conflicting library '/usr/lib/i386-linux-gnu/libGL.so.1.2.0' is known to dpkg.
