dude it seems you have a messed up OS system, probably you tried many other things and end up with system issues or the dependencies are missing. Ensure you install those dependencies and run the commands as root user. Join our forum and post the detailed issue there.

Good article I’m stuck at step 2. I get the message Unable to locate package zlib. I’m on Ubuntu 20.04.

Sandeep B. March 24, 2021 - 4:13 am

Hi, I’ve added the steps to install zlib via apt, via deb and via source.

Rudy March 24, 2021 - 2:57 pm

Thank you very much. This worked.

I have a question if there is an update for curl do you have to uninstall the older version and then install the new one? Or is there a way to update curl? I’ve searched for it but can’t find it.

follow the steps again to update curl, nothing need to be removed.
