New systems have an issue with dh key length

[robbintt]

I just set this up on a custom client with ubuntu 18 and couldn’t download maps due to the dh key for the host:port listed under the ;repository download-mapdb command.

The cert needs upgraded to be more modern, i presume you have a 1024 bit dh key which doesn’t cut the mustard anymore. Thanks!

on more recent debian/ubuntu releases you can set

CipherString = DEFAULT@SECLEVEL=1

in /etc/ssl/openssl.cnf to work around it.

you probably could just delete that line entirely actually, that should be the default and the debian devs upped it

You are correct. This is the route I took as an intermediate solution. Ideally this security bugfix still makes it through. Thanks!

You'd need to talk to Tillmen, he controls repository.

https://github.com/matt-lowe/Lich would be the right place to report it, or email him, he controls the server repos runs on
