Not update a package with apt-get upgrade

When we are going to update the system by means of the use of apt-get upgrade it updates all the packages that exist without updating. Ever we don’t want that a package gets up-to-date, due to many things, we like more this version, the new version isn’t compatible with anything that you need, etc.

There is a small trick in order that there are not updated the packages that you want and it is add to file /etc/apt/preferences the following lines:

Package: package
Pin: version X.XX
Pin-Priority: 999

This way the version that you have put in this file will be the one that you still have installed. This also can be worth if you use several repositories and want to install a specific version of some package, with these lines, it will install from repositories the chosen version.
