in my company, there are several instances that are being backends for production, testing and other purposes. I am also a new employee in the company. Recently, all of the instances suddenly cannot receive any update using git or apt-get.
- When I use
git fetch --all, the result is:
fatal: unable to access 'https://[...].git/': server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none
After I saw the post, I use git config --global http.sslverify false and git fetch all again. the result is:
fatal: unable to access 'https://[...].git/': The requested URL returned error: 403
error: Could not fetch origin
That's very weird because I don't know it's a certification issue or user permission issue. Or just at the end it's a certification issue.
- Someone suggests that using
sudo apt-get updatein this link, When I usesudo apt-get update, there are lots of errors:

It is really appreciated if anyone could provide some hints/ solutions for me because I have worked on these issues for days! The dis is Ubuntu 16.04.7 LTS, our team has used Let's Encrypt for certificate, thanks so much.
git config http.sslverify false, with or without--global, is a wildly dangerous tool. Don't use it lightly.)
