Update Ubuntu - self hosting Sitsi on my LAN PC

I have a self hosted Jitsi on my LAN pc.
I encounter system messages to update Linux packages.
Is it safe to follow these messages or there are specific guides for that.
Besides, should I update Jitsi packages and how?
Thx

Yes, it should be fine. I’m unaware of any linux package right now that breaks Jitsi.

When updates are available, you’ll be notified in your command console. At which point, you just need to do:

sudo apt update
sudo apt upgrade

Not that you will lose some customizations (look and feel stuff) when you update Jitsi, so be aware of that.

Thx
