Hello there,

In addition to what has already been mentioned, I wanted to point out that CentOS Linux 8 has reached End Of Life (EOL) on December 31st, 2021.

I would strongly recommend planning either migration to another OS like Debian or Ubuntu, or upgrading to CentOS Stream.

I personally believe that the safest way to do this is to follow these steps here:

  • Spin up a new Droplet with the desired OS
  • Install the necessary services (webserver, sql server, etc.)
  • After that using rsync for example copy over your files and migrate your databases
  • Then test your website and server fully to make sure that everything is working as expected
  • Finally, change your DNS to point to the new Droplet

Hi @MassiveCyanSeal,

I haven’t seen such an issue before however after some research, this seems to be a bug with nmtui. What seems to fix the issue is the

ipv4.method manual 

option.

Basically, what seems to work is:

 nmcli connection modify ether-enp1s0 ipv4.method manual ipv4.addresses XXX.XXX.XXX.XXX/24 ipv4.gateway XXX.XXX.XXX.XXX ipv4.dns XXX.XXX.XXX.XXX

Where XXX.XXX.XXX.XXX are your IP addresses accordingly to what’s needed.

Hope this helps!
