When I updated my Ubuntu system with update manager, I encountered an error, and now the update manager is stuck. The error message is:
An unresolvable problem occurred while initializing the package
information.
Please report this bug against the 'update-manager' package and
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 moonlight-tools (NewVersion1), E:Problem
with MergeList
/var/lib/apt/lists/us.archive.ubuntu.com_ubuntu_dists_lucid-proposed_universe_binary-i386_Packages,
E:The package lists or status file could not be parsed or opened.'
I googled on how to increase the cache-limit, and changed /etc/apt/apt.conf.d/70debconf to
APT::Cache-Limit "100000000"
But this solution doesn't work. The problem wasn't fixed.
What should I do to fix this problem?

Answer 1

These steps worked for me in Ubuntu 16:
Add line APT::Cache-Limit "100000000"; to file /etc/apt/apt.conf.d/70debconf
Delete all corrupted merge lists.
sudo rm /var/lib/apt/lists/* -vf
Then running an update with following command will automatically create
a good new /var/lib/dpkg/status file.
sudo apt-get update

Answer 2

Instead of adding the line APT::Cache-Limit "100000000"; to the file /etc/apt/apt.conf.d/70debconf add it to the file /etc/apt/apt.conf.d/20archive which solved the problem for me.

Answer 3

Have you tried the /etc/apt/apt.conf.d/20archive and setting the max size and max age values?

Mepis 12 Variant:
When attempting to activate all the available repositories in Mepis 12, Synaptic will gripe,
"E: Dynamic MMap ran out of room. Please increase the size of APT::Cache-Start."
and crash out on exit, subsequently refusing to restart.
Mepis users who need the full spectrum of available repos should edit the content of the "80mepis" file in the /etc/apt/apt.conf.d/ directory to read
APT::Cache-Limit "100000000";
as suggested for the /etc/apt/apt.conf.d/70debconf file in similar affected distros, as above. My Mepis 12 Final Edition installations have all, to date, required this fix in order to to enable a full complement of repositories on demand.
Heartfelt thanks to the others who have gone before. As a longtime public Mepis installer, I think cleaning the system with
rm /var/lib/apt/lists/* -vf
mv /var/lib/dpkg/status /var/lib/dpkg/status-bad
cp /var/lib/dpkg/status-old /var/lib/dpkg/status
and then doing a
apt-get update
command from the command line, all as su (aka root),as suggested above, is a very good idea too. And that is all. 0{:-)o[

Answer 5

You may attempt to clean the APT-list which may be corrupted, and then replace it with an existing, working one.
sudo rm /var/lib/apt/lists/* -vf
sudo mv /var/lib/dpkg/status /var/lib/dpkg/status-bad
sudo cp /var/lib/dpkg/status-old /var/lib/dpkg/status
sudo apt-get update

Answer 6

May be due to server resource limitation, setting APT::Cache-Limit "100000000"; didn't work for me.
My last resort stop resource intensive service for temporary and perform the upgrade.
Thanks,
