some good ideas for how to go about updating in jailmaker
and if you are wondering
https://www.reddit.com/r/termux/comments/nxhpvj/pkg_vs_apt/
We strongly recommend to use a pkg utility instead of apt directly. It is a wrapper that performs a number of tasks:
- Provides command shortcuts. Use “pkg in” instead of “pkg install” or “apt install”.
- Automatically runs “apt update” before installing a package if necessary.
- Performs some client side repository load-balancing by automatically switching mirrors on a regular basis. That is important to prevent us hitting quota limit on hosting.
is it alright to use apt?
As long as you manually run apt update before you try to install something you will be alright
