I've dropped the release note for this from the wiki page; the fix was
uploaded to quantal, so this doesn't seem to be a noteworthy issue now.

don't see any reason to think they're more likely to hit it when

skaet lamont, jibel saw the failure on hardware and VM, fresh installation,
all amd64. hggdh hasn't been able to see it though. what are the specifics
of the system you saw 1066445 on?
lamont skaet: I'd have to dig a bit, but I'm pretty sure this was an install
from this year, call it
I can confirm what LaMont Jones just wrote here.
When both quantal main and universe are in the same deb line, the crash follows.

A temporary workaround is:
echo 'APT::Cache-Start 50331648;' /etc/apt/apt.conf.d/99cache-start
This doubles the initial size of APT's cache in memory, thereby
happening to avoid this remapping problem. This will probably cause APT
to use more memory, so you should remove
Seems to have been introduced in, er, I think somewhere between lucid
and natty but I would need to be rather more awake to trace the full
history. It's probably not worth SRUing this back very far, but it
would be helpful to at least put the fix in precise.

The new apt (0.9.7.5ubuntu4) did fix this issue for me immediately.
I did not use the workaround suggested.
Instead, I removed the universe from /etc/apt/sources.list first,
then updated apt and finally reintroduced the universe back to the
sources.list.
