To compile something, I needed the
zlib1g-dev package to be installed so I launched an
apt-get install zlib1g-dev.
apt-get informed me nicely that the package was already auto-installed because of an other package, and that it understands that I want it installed explicitly now :
# apt-get install zlib1g-dev
zlib1g-dev is already the newest version.
zlib1g-dev set to manually installed.
My compilation done, I don't need it any more explicitly, so I want to revert its status to the previous one : auto-installed. This way it will be pruned automatically when it will not be needed any more with a simple
I cannot do an
apt-get remove zlib1g-dev since some packages still depends on it.
So how may I revert the package
zlib1g-devinstallation state to auto-installed ?
I know that I might edit
/var/lib/apt/extended_states by hand from
... but it just doesn't feel right.
