Solution 1:

--keyserver pool.sks-keyservers.net

SKS keyservers are deprecated and most of them are going offline. As such you will not be able to retrieve keys from them.

Instead you should use --keyserver keyserver.ubuntu.com.

No name This may be a server issue.

There is a notice dated 2021-06-21 on sks-keyservers.net stating "Due to even more GDPR takedown requests, the DNS records for the pool will no longer be provided at all."
