So I created a new VM w/ Fedora 26… did dnf installs for nano ect, then changed host name with hostnamectl command, rebooted… and thats when dnf and yum wouldn’t work. Instead I would get the error
Failed to synchronize chache for repo ‘updates’
I googled around and fiddled with a few settings here and there thinking the hostname change f’d something up (which it may have), but the host name change replicated everything was where it was supposed to be… the issue ended up being a DNS issue. I saw this when I edited /etc/resolve.conf and there was a random internal IP in there for a name server… so i deleted it and added google’s DNS server with the following lines.
- nameserver 220.127.116.11
- nameserver 18.104.22.168
- #Then restart the network
- Systemctl restart network
This fixed my issue… not sure what generated the weird DNS ip?
