Hi! I’m trying to install Julia 1.6 on a linux server, but am encountering issues with detection of, and cloning from, the registries. Something to do with git issues or an SSL error somewhere? Is this related to an issue regarding permissions on my end?

```julia
(@v1.6) pkg> add Dates
  Installing known registries into `~/.julia`

This seems to be a problem with the X509 certificate’s validity.

Do you get the same error when you do

`git clone https://github.com/JuliaRegistries/General.git`

somewhere in a temp directory in the shell?

Which Linux do you use? What’s the `git --version` and `openssl version`?

Btw. it could also be that a certificate is somehow corrupted. Those are stored in `/etc/ssl/certs`, maybe try to look for something with `ffffde80`, as reported by the error message, but I am just guessing…

EDIT: or simply run something like `update-ca-certificates`, see here for Ubuntu/Debian: [Ubuntu Manpage: update-ca-certificates - update /etc/ssl/certs and certificates.crt](http://manpages.ubuntu.com/manpages/trusty/man8/update-ca-certificates.8.html)

Alright, so it appears that I needed to use [GitError that only occurs in 1.6/nightly · Issue #39289 · JuliaLang/julia · GitHub](https://github.com/JuliaLang/julia/issues/39289) instead.
