I tried to install language-pack-sv-base through Synaptic. In the final stages it seemed to hang. I killed Synaptic and after restart I got a message to run

dpkg --configure -a

which I did. This produced the result:

Setting up language-pack-sv-base (1:7.10+20080205) ...
Generating locales...
sv_FI.UTF-8...

and just keeps on going in the terminal. I'm sure something is wrong.

What to do?
