Problem:

When I try to do install v2.0.2 , it went flawless till cloning “cyberpanel” from github. after cloning it showed “Check /swap” and then stuck there. I waited 30 minutes but nothing happeneed. then I realized I was not able to surf on internet (using that specific machine) so I finally fixed it my restarting systemd-resolved. but till then terminal exited the installation process without completing installation.

Then I tried v2.0.1. it was keep getting pip installation error. I waiter 42 retries but no use.

The I tried v1.9.x. It was same like v2.0.1. pip errors

Btw. I installed and using cyberpanel on digital ocean and it works very good.
