Issue fetching gpg keys

I was trying to fetch a key from keyserver.ubuntu.com (gpg --keyserver keyserver.ubuntu.com --recv-keys 6e85a86e4652b4e6), and kept getting the following error:

gpg: keyserver receive failed: Server indicated a failure

After some digging, I found out that it's a DNS issue affecting dirmngr and "faulty" DNS servers.

Sure enough, after adding 1.1.1.1 (Cloudflare DNS) as the DNS resolver for keyserver.ubuntu.com, the issue disappeared:

# /etc/systemd/resolved.conf

[...]

DNS=1.1.1.1
Domains=~keyserver.ubuntu.com

I'm not sure if this is an isolated issue but I'm posting here just in case.

Got the same problem and can confirm that disabling Nextdns the import work as expected.
