Could not initialise the package information

[steven rhodes]

hi

I reinstalled Ubuntu 10.04 after a problem with external usb devices, which didesolved the problem and left me with no root and more problems...
After using computer janitor and synaptic package manager my update manager no longer works... and gives me this error message.
Could not initialise the package information

An unresolvable problem occurred while initialising the package information.

Please report this bug for the 'update-manager' package and try to include the following error message:

'E:Dynamic MMap ran out of room. Please increase the size of APT::Cache-Limit. Current value: 25165824. (man 5 apt.conf), E:Error occurred while processing libtntnet-dev (NewFileDesc2), E:Problem with MergeList /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_lucid_universe_binary-i386_Packages, E:The package lists or status file could not be parsed or opened.'

i have been looking for solutions on the forums but seem to be getting my self future away form a solution any help would be appreciated
Steve
