Which packages are on hold? :: kanotix.com :: GNU Linux Live system based on Debian, optimized for HD-install and high performance

That is fast resolved with this command sequence:

# dpkg --get-selections |awk '$2 == "hold" { print $1 }'

thanks to slh

To set packages on hold, use:

# echo <packetname> hold |dpkg --set-selections

To allow updates to the packages again, use:

# echo <packetname> install |dpkg --set-selections
