Native libraries not working on Ubuntu

[danwalmsley]

I'm trying to use libgit2sharp on Ubuntu (inside docker container)

I ran mono with MONO_LOG_LEVEL="debug", there seems to be a problem loading the native libraries:

Can anyone help?

Like the loader says, you're missing libcurl. Install the package that gives you libcurl.so.4 which will either be libcurl3 or libcurl4 depending on whether Ubuntu has changed the package names.

Carlosmn thank you so much for that:

apt-get install libcurl3 worked.

Iv been trying for hours to install libcurl and nothing I found on google worked. Much appreciated.
