Hi,
I'm running NR on a virtual machine with Debian. I was running Debian11 and NR 4.0.6. I upgraded Debian from 11 to 12 and with the command:
npm install -g --unsafe-perm node-red
I tried to update to V5. But all that I got is 4.1.1.
And I got the remark that --unsafe-perm deprecated is.
What to do to update to V5?

Homepage states: Latest version: [v4.1.1 (npm)]

What makes you think that there is a v5 of node-red?

I think I saw that somewhere... I must be mistaken... Sorry...
Oh and I did not get deprecated on the --unsafe-perm but I got :
Unknown cli-config --unsafe-perm. This will stop working on the next major version of npm

My understanding is that --unsafe-perm is no longer necessary with current versions of npm.
