Can't resolve hostnames ubuntu 18.04












0















Since earlier today i can't resolve any hostname anymore. apt-get update/upgrade fail because of this for example.



I have tried to lookup the IP for some of the sources in /etc/apt/sources/list on another so far machine and adjust to these but this gives several security and other error messages.



I do not have resolvconf installed so can't use this (as suggested when googeling this issue).



I have tried changing netplan yaml from static to DHCP but so far everything i have tried and found online has failed.



I am hoping someone can help me troubleshoot further as i really don't want to reinstall the system completely again including the setup.
