top?
df -h?
free -m?
anything relevant in /var/log/syslog?
any segfaults in dmesg?
Other, probably peripheral, issues:-
* you have an invalid sources.list.d entry.
Fix with (as root):-
mv /etc/apt/sources.list.d/opera.list.save /etc/apt
* You 'might' not using the closest/fastest repositories. There are ways
to check, automagically choose the quickest ones. All explained
previously here and on wiki.debian.org. "# tcptraceroute" to those
repositories will give more information (I don't know your timeout
settings).
If you state your ISP the list 'might' be able to recommend a mirror
that is:-
;close and fast.
;and that your ISP doesn't count against your transfer totals.
* With opera repositories - stable no longer means "squeeze". This (most
likely) does not cause the problems you are experiencing - but it won't
help things.
Change it to "squeeze"[*1]
There should be no problems with you commenting out opera repositories
until you've resolved your current difficulties.
Hope that helps to sort out minor contributing factors to slow updates,
from the main cause
[*1] see - http://deb.opera.com/opera/dists/ for more fine grained
compatibility control options than "[currently]stable"
Kind regards
