git clone fails with "An unexpected TLS packet was received" error

[thomas duriez]

I just updated from 16.04 to 18.04 beta.

This is the error message I get when I try to clone a repo:

fatal: unable to access 'https://github.com/xxxxxxx/yyyyyyyyy.git/': gnutls_handshake() failed: An unexpected TLS packet was received.

I cannot clone repositories on internet (tried on github and overleaf) when I used to have no pb.
This applies to https repositories (Couldn't try over ssh, IT decision).
I built this version of git to use libcurl4-openssl instead of libcurl4-gnutls to no avail but with a different error message though:

fatal: unable to access 'https://github.com/xxxxxxx/yyyyyyyyy.git/': error:1408F10B:SSL routines:ssl3_get_record:wrong version number

I purged packages and deleted .gitconfig, without results.

Sorry, this is solved, I just had to set

git config --global https.proxy

why this was not retained when upgrading from 16.04 or why it needs now to be set (the $https_proxy environment variable is correctly set) is still a problem though.
