A unresolvable problem occurred while initializing the package information.

Linux ubuntufiechtl 2.6.20-16-generic #2 SMP Thu Aug 30 23:16:15 UTC 2007 x86_64 GNU/Linux

Added the debian source list to Synaptic source list third party and got this message.

An error occurred
The following details are provided.

E:Dynamic Mmap ran out of room
E:Error occurred while processing slurm-llnl (NewVersion1)
E:Problem with MergeList /var/lib/apt/lists/
ftp.de.debian.org_debian_dists_sid_main_binary-amd64_Packages
E:The package lists or status file could not be parsed or opened.
E:_cache->open()failed, please report.

I will attempt to remove it to resolve the problem.

Cannot remove source list from synaptic repoitory.

Used this command:
sudo gedit /etc/apt/sources.list
commented out the last line, the line added
 deb http://ftp.de.debian.org/debian sid main,
which was where the error messages began.

Also, was noticing problems downloading prior to these error messages. Could not "download" but could "open" source files, double clicking, extracting. I have been attempting to install GyachE and I might add without success.

Did:

sudo apt-get update; failed.

sudo apt-get install -f; failed.

Attempted to open update icon in top panel. No success until I commented out last line of /etc/apt/sources.list. Even though the update indicates updates available none were listed.
Trying above commands again.

Attempting to install gyachE, dependency

Failed to check for installed and available applications

This is a major failure of your software management system. Please check for broken packages with synaptic, check the file permissions and correctness of the file '/etc/apt/sources.list' and reload the software information with : 'sudo apt-get update' and 'sudo apt-get install -f'.

This seems to have fixed the problem. I'm filing it to help othes understand. Bug fixed, if that this in fact was a bug. Sorry if my lack of understanding wasted your time.
