    @cagatay as @downpw stated, there isn’t a native tool that will do this for you. You’d need to either develop your own or ask the nodebb team to assist which will be a paid exercise.

    @cagatay The most reliable way to upgrade Node.js on Ubuntu depends on how you originally installed it. Method 1: Using NVM (Recommended) If you already use Node Version Manager (NVM), upgrading is simple. NVM allows you to keep both versions and switch between them if needed. Install Node 22: nvm install 22 Switch to Node 22: nvm use 22 Set it as your default: nvm alias default 22 Verify the change: node -v Method 2: Using NodeSource (PPA) If you installed Node.js via apt using the NodeSource repository, you need to update the repository script to point to the new version. Remove the old NodeSource list (optional but cleaner): sudo rm /etc/apt/sources.list.d/nodesource.list Download and run the NodeSource setup script for Node 22: curl -fsSL [https://deb.nodesource.com/setup_22.x](https://deb.nodesource.com/setup_22.x) | sudo -E bash - Install/Upgrade Node.js: sudo apt-get install -y nodejs Verify the installation: node -v Method 3: Using the ‘n’ Package If you have npm installed, you can use the n interactive manager. Clear the npm cache: sudo npm cache clean -f Install the ‘n’ helper: sudo npm install -g n Install Node 22: sudo n 22 Update your shell: hash -r Troubleshooting Permission Denied: If you see permission errors using Method 2 or 3, ensure you are using sudo. Path Issues: If node -v still shows version 20 after upgrading via NVM, restart your terminal or run source ~/.bashrc. Conflicts: Avoid mixing these methods. If you switch from apt to nvm, it is best to sudo apt remove nodejs first to avoid path conflicts.

    I’ve noticed that I’m the only one subscribed to the push notifications on this site. If you were using NTFY previously, and have noticed that you’ve not had any alerts for a while, it’s because this feature has been disabled. You’ll now need to use the push notification to replace NTFY as mentioned in the first post.

    @Panda said in Smart Widgets: So why is that, or conversely why would the function to expose username ever be required, as it seems app.user is already an available global object? It is, yes, but not if you are using it outside of a widget. The function I wrote is also historical and comes from the 2.x train

    @Teemberland great spot ! You should create a PR for that so they can include it in the official repository. Just be aware that any subsequent releases will overwrite your fix without the PR.
