I wanted to install Webmin on the server (VPS).
To do this, I entered the command as described on the Webmin website.
curl -o webmin-setup-repo.sh https://raw.githubusercontent.com/webmin/webmin/master/webmin-setup-repo.sh
sudo sh webmin-setup-repo.sh
The question “Setup Webmin stable repository?” appeared.
I confirmed this with “y”.
Then a message appeared stating that there was an error downloading the developer key.
What should I do?
