if anyone would like to help test the latest version of the Pi/Debian install script then I would be most grateful for some extra testing... Of course it should work fine... but the whole point is to find out where it doesn't - so make sure you don't do this on a critical system - and do have backups of your flows etc...
The main changes (so far) are - if anything less than node12 installed - it will update to node14 (by default) - if 12 or above is installed default action is to leave alone.
There are now some more command line switches -
--node12 will force reinstall of node12 and likewise
--node14 will force install node14. (We'll add node16 as and when)...
There is also now a
--restart option to auto restart the service if the install succeeds.
To see all command line switches just add
--help to the following
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/v2/deb/update-nodejs-and-nodered)
Feedback (and/or suggestions) here please.
