Pgp host not found error while installing Ardor client as Docker

I am having problem while running docker image. It seems, can't get PGP key from

Docker run exits with the following error:

2021-07-26 22:30:22 (43.0 MB/s) - ‘’ saved [833/833]

May be is not live anymore? Can i do to skip PGP validation? Or any other solution.


Indeed, seems like that server is down. I will check some workarounds.

Thank you. I also tried this nonofficial image. Docker Hub
But it does not support the latest crypto DB version which is #179 and it seems to support DB version#178. Do we have a chance to get previous versions of the DB somewhere?

That would be probably an older version of the software not compatible with the current blockchain.

We have updated the Ardor Docker image. This should fix the issues with the key server.

Thank you.
