Log and give solutions in OVH Debian/Ubuntu common issues when using vRack and/or Docker containers
For some reason, after your initial setup and after you attached your OVH instance to a private network, you can loose access to internet.
For example: ping google.com timeouts.
sudo nano /etc/resolv.confThe file might contains something like that:
nameserver 213.186.33.99
nameserver 1.1.1.1
nameserver 1.0.0.1
# Too many DNS servers configured, the following entries may be ignored.
nameserver 213.186.33.99
nameserver 1.1.1.1
nameserver 1.0.0.1
nameserver 213.186.33.99
nameserver 1.1.1.1
nameserver 1.0.0.1
search .
Just remove all of this and change it to:
nameserver 127.0.0.53
options edns0 trust-ad
search .
First, check you got the issue:
ls -la /etc
You should see /etc/resolv.conf that links to :
lrwxrwxrwx 1 root root 32 Oct 4 04:35 resolv.conf -> /run/systemd/resolve/resolv.conf
which is not correct.
If have ANY other symlink, don't use the following method. If you have this symlink, you can go further:
Permanent solution:
a.
sudo nano /run/systemd/resolve/stub-resolv.confnameserver 127.0.0.53
options edns0 trust-ad
search .
b.
sudo mv /etc/resolv.conf /etc/resolve.conf.backup
sudo ln -s /run/systemd/resolve/stub-resolv.conf /etc/resolv.conf
sudo netplan try
sudo netplan apply
sudo systemctl restart systemd-resolved
#... I recommend to reboot your system
sudo reboot
