I am trying to Install aegir on Ubuntu 18.04 and 20.04 lts to manage drupal sites.
Every time I try to update the server and install aegir it displays the following error
me@userpc:# apt-get update

I tried to Get the renewed key using the following command but it doesn't seem to work ...
curl http://debian.aegirproject.org/key.asc | sudo apt-key add
sudo apt-get update
Any help will be appreciated.
