So the second challenge https://learn.kodekloud.com/user/courses/linux-challenges/module/b1104b85-a11a-47b3-a012-8b6a0ea815a8/lesson/a12d6774-3acc-4d78-9744-a7181c0eb361 is having an issue to request intenet in general. I went to /etc/resolv.conf and add the nameservers 8.8.8.8 8.8.4.4 and 1.1.1.1 separted each one by a new line in the file, and the container is unable to get internet properly. When I do sudo dnf update it only updates the first repo, but for the extra repo, the container just stay in waiting and waiting for a respond. I mostly sure this lab is buggy. Please if that’s the case fix it so I can train for my sys admin certification 
It’s working. I just re-checked the solution I created for this almost 3 years ago, and it’s still working
However, dnf is sloooow in this lab, even when the resolv.conf is correct. You just have to wait…

Thanks for the info @Alistair_KodeKloud . So it usually does take that 2 minutes to do the db package update and package installation ?
