@dmitry-ganyushin do you still need this?

[scottwittenburg]

The package manager makes us pick a TLS backend, as described in not very much detail here. Which version of libcurl-dev- do we want?

Package libcurl-dev is a virtual package provided by:
  libcurl4-openssl-dev 7.68.0-1ubuntu2.19
  libcurl4-nss-dev 7.68.0-1ubuntu2.19
  libcurl4-gnutls-dev 7.68.0-1ubuntu2.19
You should explicitly select one to install.

Since he will be using Python libcurl as well maybe openssl?

Do you know what python package @dmitry-ganyushin will be using? For example I found pycurl is available via apt, and depends on the gnutls variant:

# apt-cache showpkg python3-pycurl
Package: python3-pycurl
Versions: 
7.43.0.2-1ubuntu5 (/var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_focal_main_binary-amd64_Packages.lz4)

@vicentebolea @dmitry-ganyushin Let me know what you want to do here. If "Python libcurl" refers to a specific python package, let me know which one, and I can look into it. Or I can just go with the openssl version of libcurl4 (libcurl4-openssl-dev) and hope for the best.

[vicentebolea]

I would say go with the gnutls variant as ubuntu python use this, in a future task we might have to install also that package for testing the python bits using libcurl
