Hi,

you can use /etc/apt/preferences to forcibly downgrade your distribution.

I think that you can just put the following lines in the file and update your
sources:

Package: *
Pin: release n=slaine
Pin-Priority: 1001

For more information, see

$ man apt_preferences

Maybe you already know that, but to upgrade the sources you must edit 
/etc/apt/sources.list to point to slaine (4.5)

I think that doing

sed -i 's/dagda/slaine/' /etc/apt/sources.list

ran as root, should work.

The file should look like this:

# Trisquel repositories for supported software and updates

deb http://es.archive.trisquel.info/trisquel/ slaine main
deb-src http://es.archive.trisquel.info/trisquel/ slaine main
deb http://es.archive.trisquel.info/trisquel/ slaine-security main
deb-src http://es.archive.trisquel.info/trisquel/ slaine-security main
deb http://es.archive.trisquel.info/trisquel/ slaine-updates main
deb-src http://es.archive.trisquel.info/trisquel/ slaine-updates main
deb http://es.archive.trisquel.info/trisquel/ slaine-backports main
deb-src http://es.archive.trisquel.info/trisquel/ slaine-backports main

Best,
