I broke my cloudron

[AartJansen]

I installed netdata into ubuntu with apt install, didn't want to keep it & then removed it and autoremoved the dependencies it left behind.
This seems to have uninstalled node.
I tried apt install npm, but its a different version now (10.1.0) cloudron wants (20.18.0)
I tried npm install -g n 20.18.0
but it cannot find such a version.
What do?

oh nevermind. I read the "you can try" instructions in the output

sudo ln -sf /usr/local/node-20.18.0/bin/node /usr/bin/node
sudo ln -sf /usr/local/node-20.18.0/bin/npm /usr/bin/npm
sudo systemctl restart box

And that seems to have gotten it going again. /phew
