Quick tip to help you to manage packages on a Debian distribution:
How to perform an upgrade (apt-get upgrade) without upgrading one or more critical packages?
I’m running a Debian server with a Groundwork monitoring tool. Groundwork requires specific MySQL packages that cannot be upgraded.
# cat <<END | dpkg --set-selections mysql-common hold mysql-client-5.0 hold mysql-server-5.0 hold END # dpkg --get-selections "*"|grep -e "hold$"
You can now safely keep your system up-to-date!
