You update all the packages when there is an update available. But how can you restrict debian to be updated for only selected packages. How you’ll stop it from updating certail packages. I assume you’re using dpkg to update the debain. Follow the procedure to prevent package from update.

Using dpkg, you can put a package on hold

echo “package hold” | dpkg --set-selections

Example

echo “apache2 hold” | dpkg --set-selections

Also to remove the hold, type the following :

echo “package install” | dpkg --set-selections

Follow the steps as above and you’ll be able to prevent package from being updated.
