I don’t know. You originally did not have DNSSEC configured, so nothing is going to work with that. Then after that we discover that you can’t use sudo and we don’t really know why, because you had to use sudo before to run updates.
I recommend installing absolutely nothing, running sudo apt update && sudo apt upgrade, disabling root logins and password logins in sshd_config, then install MiaB, see what happens.
Hi again. As u recommended me earlier I changed my vps provider and reinstall my miabox only before using apt update\upgrade. And again i got the same problem with my dnssec ds record. I added it to my namecheap account and the miabox status agai give me info that my ns1\ns2.box.example.com is not set and dnssec ds record is not set.
