If 'startx' doesn't work, you need to install xorg & a WM/DE.

(It's been a while since I last installed it to a RPi....)

They tried that before, & lost a lot of their programmers, & users, & created a lot of bad blood!

Haven't they learned their lesson yet! - Linux is about freedom of choice!

Thankfully, it caused Devuan to be born in the first instance, if they do it again, many users will (possibly) ditch Devuan as well, if it isn't an easy job to continue using Debian as a base!

Ventoy will start up in either MBR or UEFI, depending on your computer, & it starts the distro as it would start if it was the only one on a pendrive, all boot options of the distro remain available.

I regularly ran Devuan/XFCE on a 2GB ram / 1.2GHz dual core thin client, I even ran it with just 1GB ram as an experiment on a single core thin client, it was a little slow, but even the internet was usable.

It's lightning fast on my 2GB ram converted Chromebook.

Welcome aboard.

Welcome aboard.

Why not tell us something about yourself.....

I'm guessing the new versions are for the upgraded libc, which I have already done on my installs yesterday.

Welcome back, & congrats on getting your own home.

Only thing about upgrading to Daedelus is to add a line to sources list, because Debian has separated out the non-free wifi stuff, I think it was, but it's in the forum somewhere.

Your system is 'freezing up'.

Sounds like faulty electrics/power, check out your wiring for something loose, (or perhaps it's trouble with your power company/supplier?).

If they aren't the problem then it looks like it could be a problem with your ram/faulty chips(?).

Processor may be overheating & shutting down the computer(?)

It may be something to do with the above security 'features' - maybe try removing 'secure boot', or possibly that TPM module(?).

If it's your own personal system that you want to duplicate, use a 'snapshot', these can be installed to bare metal - otherwise it sounds like you want to 'mirror' the repos.

If your user doesn't own the directory, you need to use sudo or the root account.

But, you could change ownership of that mount point to your user, then you can do what you like with files & directories on it.
