Don't upgrade specific packages

From time to time I don't want to upgrade some packages on my debian server (because there is a bug with the new version or some other reasons) but I still want to do the other updates.

APT is able to handle that but it's not really easy to do (and to remember). There is a utility called wajig that simplify that a lot (wajig aim is to do all the package handling stuff simpler than apt and dpkg).

Install wajig as usual:

$ sudo apt-get install wajig

And here is how to use it for holding a package, unholding it or list all packages that are on hold:

$ sudo wajig hold
$ sudo wajig unhold
$ sudo wajig list-hold
