Question

Disable "/etc/systemd/resolved.conf.d/DigitalOcean.conf"

On every boot/reboot of an Ubuntu Linux (21.10 at the moment) droplet, DigitalOcean restores this file:

/etc/systemd/resolved.conf.d/DigitalOcean.conf

I can comment-out the lines inside and they will be uncommented on reboot. I can delete the file and it will re-appear on reboot. The file causes problems (https://github.com/systemd/systemd/issues/20119) and there must be some way to disable it.

Aside from writing my own script that auto-deletes the file on boot, how can I disable that file from every appearing in the first place?

Hello there,

Have you tried to make the file immutable using chattr?

chattr [operator] [flags] [filename]

  1. chhatr +i /path/to/file

A file is set with ‘i‘ attribute, cannot be modified (immutable). Means no renaming, no symbolic link creation, no execution, no writable

To remove the attribute:

  1. chhatr -i /path/to/file

To check the attributes of a file:

  1. lsattr /path/to/file

Hope that this helps!
