Recently I got a message from my firewall saying:
the md5sum comparison test FAILED for /usr/local/bin/certbot-auto. Does this file auto renew itself also, besides certificates?
By the way, I tried commando:
but it does not output anything. When I follow instructions to test integrity from here, I get the following error message:
gpg: requesting key CD9775F2 from hkp server pool.sks-keyservers.net
gpgkeys: HTTP fetch error 7: Failed to connect to 2001:ba8:1f1:f2d4::2: Network is unreachable
So I am getting a bit suspicious now. What is going on? Any hints/comments are appreciated!
