Install particular version of package?

[Steffen Grunewald]

Hi all,

since I seem to be the only one who ever faced this question, I'll also
be the only one to answer it...

It is possible, but mistyping the version (or specifying one that has been
removed from the repository) will result in the infamous "25600 25600" error,
causing not only this particular package missing from the installation but
a whole lot more!

This way is much safer, and it saves the trouble of getting things right
when an upgraded package fixes the broken one - if you check the installed
version ("dpkg -l package | awk '{print $3}'") and in that "case" *only*
perform the downgrade.

HTH someone else,
