Hi all, On Ubuntu 20.04, see my following relevant git variables settings: $ env |grep GIT GIT_SSL_NO_VERIFY=1 GIT_HOSTING=git@xxxxxxxxxxxxxx GIT_DISCOVERY_ACROSS_FILESYSTEM=true I don't set the `GIT_HOSTING' variable at all. Then where does it come from and what's the function of it? Regards -- Assoc.
