My ultimate goal with learning this is I want to self host my own Monero node and eventually maybe even self host emails and after that learn docker as well.

But I am a long, long way from there.

Where do I start with something like this if I have no experience with networking?

Should I just start with learning a VPS? I just don't like the idea of me not being able to physically control the server because I think one day Monero might be outlawed or something.

But I'll do whatever I have to to learn.

[Solved] just had to create a new partition and then it lets me select FAT.

I'm not sure what happened, I remeber using gnome disks to do this before but it isn't working now now the only options I get are (MBR/DOS) or (GPT) and neither one will let me access the actual USB afterwards in anything other than GNOME disks. I can't use file explorer and add anything to it.

What is going on here? I swear this worked well before but now something has changed suddenly and I can't get it to work anymore.

When I restore a Debian disk image to the USB it will finally show up in the file explorer but I can't add anything to it and the only options I get to format it are those ones that won't let me access it in the file explorer and actually use the USB.

What am I doing wrong?

[Solved] So I disabled the CD ROM repository using the software and updates application on Debian 12 because it kept asking me to insert the CD ROM when I would try to install stuff.

After disabling it I used Aptitude to update the packages I had already installed but I noticed that before I disabled the CD ROM repository it told me that because I didn't have it inserted that it used some older versions of software.

After removing the CD rom repository it just updated everything and didn't show that message.

My concern is that I know Debian uses some older versions of stuff because of its stability and I read very briefly about "Franken Debian" situations where people use versions of stuff that weren't intended to be used with the stable version of Debian.

Did I mess up by doing that and create a situation like that? And if so, after a fresh reinstall when I get here again is virtually mounting the USB stick I have the Debian DVD ROM on an option for it to stick with that CD ROM repository? (I don't have a physical CD ROM on this machine)

I see that it can be slower because of having all the dependencies included with the flatpak itself instead of relying solely on whats installed on the system. I read that this means it isolates or sandboxes itself from the rest of the system.

Does this not mean that it can't infect the rest of the system even if it had malware?

I have seen people say that it isnt good for security because sometimes they force you to use a specific version of certain dependencies that often times are outdated but I'm wondering why that would matter if it was truly sandboxed and isolated.

Do they mean that installing flatpak itself is a security risk or that also specific flatpaks can be security risks themselves?

[Solved] just had to log out and back in Original post: I'm running Debian 12 and I set a separate root password from my username password.

When trying to install a .deb file I noticed that it said I was not in sudoers file so I looked it up and tried the command SU and successfully entered my root password.

The I tried doing

sudo usermod -aG sudo [username]

And then I verify the addition of the user to the sudo group with

groups [username]

And this does indeed show that I am in the sudo group however when I try to install a .deb file after that or even sudo apt update its still telling me I am not in sudoers list.

Any ideas what I'm doing wrong here?

I went with GNOME just because I'm used to it and want stability as my main focus but I was wondering if using one DE over another can affect security or privacy at all? Or is that all dependant on the distro you are using?

(Dell Optiplex 3070 mini) Edit: Successfully installed thanks to all of you! In this specific case all I had to do was change from RAID to ACHI which I was able to do in the bios settings themselves. A warning to anyone who might do this if you want to keep windows I believe you have to edit the windows registry somehow but I did not care to keep windows at all so simply changing boot order to boot the USB with Debian installer first and then change from RAID to ACHI and boom, the windows partition will be discoverable.

Original post: What am I doing wrong here? The computer has Windows 11 on it but I don't want to use it I want it all the way off the machine.

Can this installer not overwrite the Windows OS with Debian? Edit: Just want to say thanks to all of you I'm going to experiment around with the advice you all have given and see how it works out! Absolutely love the passion and helpfulness of this community here on Lemmy for real!

On Debian's website it is saying to write the image to the USB stick I should use a bash script "# cp Debian.iso /dev/sdX

sync"

Is there another way to do this without using root access?

So I've never actually used a machine with UEFI before I've always been on older machines with BIOS.

I got a Dell Optiplex 3070 Intel core 9500T (gen 9) 2.1 GHz 16GB ram 256gb SSD but it has windows 11 on it.

I hate Windows, and I don't want any trace of it left on my machine. I'd prefer Debian but would even take Ubuntu over Windows What is the best guide for this for someone who has never messed with UEFI before?

I'm wanting to run my own SimpleX chat server and set up a Monero node as well.

Can this be done on the same machine? I was considering getting a mini PC to do this so it wouldn't be too much of an issue with it being always on.

Or should I take a different approach and set up both separately on two different machines like a raspberry pi or something?

As I'm sure you can tell I don't have a lot of experience with self hosting anything but want to get into it to help strengthen the networks of these communities I care about.

Specifically for gaming and streaming in HD? Would I be able to share play games still as well or is that not happening even if I get the better Spitz router?

I want to use my MiG switch dumper to copy a game and have me and my buddy play them at the same time.

If we both play the same one online at the same time do we risk a ban?

I noticed that previous articles about it mentioned you could actually fake certificates and make it seem like two different games were playing? Does anyone know if that's still a thing?
