2022-05-10 17:07:15 VERIFY ERROR: depth=0, error=CA signature digest algorithm too weak:
2022-05-10 17:07:15 OpenSSL: error:0A000086:SSL routines::certificate verify failed
I use openvpn (with 3 configuration files: .ovpn, .p12, .key, from my terminal: sudo openvpn with these parameters: --config --pkcs12 --tls-auth).
Everything was working before upgrading to latest Ubuntu version. Then no connection possible and a lot of errors like that in the quote.
I requested a new certificate from our sysadmins, and the problem remains. It was not a problem of expired certificate.
I see this seems to be related to OpenSSL 3.0. And other people have the same issue.
Our sysadmin said I should solve it on my computer for the moment. They will solve it on the server later.
I already tried this: https://bugs.launchpad.net/ubuntu/+source/openssl/+bug/1960268/comments/32
but no change.
Can you help me to solve it, please? I am blocked in my work by this issue for 2 days already. Thank you. (Note I am really bad when I need to set/configure things... :) )
