Hello,
I could not install AdBlock Plus (which I use on Firefox) on the n810. I got this message:

Installing adblock-plus-webaddon 0.0.1-1
Failed to fetch http://browser-extras.garage.maemo.o...0.1-1_all.deb: Could not open file /media/mmc2/.apt-archive-cache/partial/adblock-plus-webaddon_0.0.1-1_all.deb - open (30 Read-only file system)
W: Not using locking for read only lock file /media/mmc2/.apt-archive-cache/lock
W: Not using locking for read only lock file /media/mmc2/.apt-archive-cache/lock
file:///media/mmc2/tmp/Adblock%20log.txt: Read only file system

I do not have greasemonkey installed.

It is just a mistery, I cannot figur out what is wrong. Could it be linked to the blocked/corrupted internal memory?

Thanks,
Antonio
