I want to install zlib on Debian 6. For this, I think I would use apt-get install, but I don't know which package to use. The package zlib doesn't exist, and if I install zlibc (which sounds most appropriate), running zlib -version brings up the error command not found. (I used apt-file search zlib to find zlibc.)

Is there another package which contains zlib, and how do I find this package?


A zlib command does not exist:

$ dpkg -L zlib1g

It is a library.

If you are searching for anything use apt-cache search.

And if you need a command to compress use either gzip or zip.

sudo apt install zlib1g


sudo apt install zlib1g-dev

as well.

  • Thank you for your answer! When I use apt-get install zlibg1, I get "zlibg1 is allready the newest version"... After installing zlib1g-dev, "which zlib" is still empty.

  • I'm noticing a /usr/lib/libz.so. Maybe Debian changed the name of it.

    If you're using the zip extension on the docker php image, you'll need zlib1g-dev
