Terminal: apt update/upgrade, can I ?

Hi,

A simple question, need to do "apt update/upgrade" a few times?
Or I don't do this?

When i do "apt list --upgradable", i have somes apps...

Question maybe silly, but I do not want to do bull....

No, updates to the system are handled by system-image. The system is read-only which prevents the use of apt for updates.

If you'd like to install applications using apt, we have the Libertine system which can be accessed through Settings->Libertine.

Ok thank you
I wouldn't do that

@Bourinov Just edited a few letters from your first post. No swear words, profanity etc. Hope you don't mind Thanks.

So sorry...
I use a translator, I check but this word is passed off.
Now I know this word is forbidden and swear word. I learn at the same time

@Bourinov No problem at all. I've had issues the other way with translator apps
