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

N: Updating from such a repository can't be done securely, and is therefore disabled by default.

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.

At the moment, Aegir 3 is minimally-maintained. Vendors offering support are Omega8, Consensus, ThinkDrop, and Symbiotic (who maintains some components at https://github.com/coopsymbiotic). Find them all at https://docs.aegirproject.org/community/services/.

For on-going support (as Debian packages are no longer maintained):

Aegir 5 is a complete rewrite in development (https://gitlab.com/aegir/aegir/), but progress is slow due to insufficient funding. Get in touch if you'd like to help with this initiative.
