Why does the "All mirrors were tried" error occur on CentOS?

Question

linux

Good day!

I plan to install GitLab on CentOS 8 according to the official instructions from the GitLab website.

I add a repository:

curl https://packages.gitlab.com/install/repositories/g... | sudo bash

I install:

sudo EXTERNAL_URL=" https://gitlab.mysite.com " dnf install -y gitlab-ee

I get a response:

Cannot download gitlab-ce-13.12.1-ce.0.el8.x86_64.rpm: All mirrors were tried

Launched several times, deleted the repository and added it again - to no avail.

What is the problem?

If you need to show what conclusion - write, I will provide.

Answer 1

What's incomprehensible? The installer checked all the mirrors available to him to download the package and could not contact any of them (judging by the log, there was one), that is, at the moment the mirror was unavailable
