| + | ===== Updating resolv.conf ===== | ||
| + | |||
| + | ''/etc/resolv/conf'' is now a symlink as below:- | ||
| + | |||
| + | <code bash> | ||
| + | root@argon:~# ls -l /etc/resolv.conf | ||
| + | lrwxrwxrwx 1 root root 39 Apr 3 08:41 /etc/resolv.conf -> ../run/systemd/resolve/stub-resolv.conf | ||
| + | |||
| + | root@argon:~# ls -l /run/systemd/resolve/* | ||
| + | -rw-r--r-- 1 systemd-resolve systemd-resolve 633 Apr 3 12:04 /run/systemd/resolve/resolv.conf | ||
| + | -rw-r--r-- 1 systemd-resolve systemd-resolve 760 Apr 3 12:04 /run/systemd/resolve/stub-resolv.conf | ||
| + | </code> | ||
| + | |||
| + | Two choices seem to exist, the resolv.conf file is the one updated by netplan, so let's use this:- | ||
| + | <code bash> | ||
| + | root@argon:~# ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf | ||
| + | ln: failed to create symbolic link '/etc/resolv.conf': File exists | ||
| + | root@argon:~# mv /etc/resolv.conf /etc/resolv.conf.orig | ||
| + | root@argon:~# ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf | ||
| + | root@argon:~# rm /etc/resolv.conf.orig | ||
| + | </code> | ||
| + | |||
| + | You could just use ''ln -sf'' to force the link creation, but if something goes wrong, you loose the original file. | ||
| + | |||
| + | Test with ''dig'' or ''nslookup'' and resolution should work as expected. | ||
