Can't Restart Nextcloud after Disk full fixed

[girish]

@Shai https://docs.cloudron.io/troubleshooting/#unbound

[Shai]

sudo systemctl status unbound
Unit unbound.service could not be found.

[girish]

@Shai are you running this on web terminal or SSH ? It should be run on SSH. How can unbound disappear?

[Shai]

SSH, unbound seems to be completely gone. nothing at /etc/unbound

[girish]

Might be best to install unbound and ssh then. After that, run /home/yellowtent/box/setup/start.sh

[Shai]

Actually when I said that unbound had disappeared I was wrong. I was logging into proxmox and not into the vm instance that Cloudron is installed on.

So here is what I get when I run sudo systemctl status unbound

unbound.service - Unbound DNS Resolver

Here is the results when I run sudo journalctl -xe

[girish]

@Shai ah nice, so did you try https://docs.cloudron.io/troubleshooting/#unbound already?

[Shai]

@girish

unbound-anchor -a /var/lib/unbound/root.key
systemctl restart unbound

That solved it. Thank you.

[Shai]

p.s. @girish Do you think I need to worry that I installed unbound on my Proxmox server when it wasn't already installed. Would it be best to uninstall it? So far that server is behaving normally. (Understood that this question is better for Proxmox support, but since I'm here I thought I'd ask.)

[girish]

@Shai yeah, better to remove it. On ubuntu, installing packages also enables them. So, this might cause problems in the future.
