JoelJ , 11 months ago in whats so good about arch compared to linux mint?

Just to chime in, I first tried arch because some youtuber I followed recommended it, but after 5 years I would say I’ve stayed with it for the AUR and the community. The AUR has almost every app I’ve ever needed, and whenever I have a problem there’s always a solution on one forum or another, to the point where I can usually just copy and paste it into the terminal and it’s solved!

AUR is kind of the worst feature Arch offers and I am not actively using Arch right now anyway. Because its used for the wrong purpose: “install any app you need/want”. Thats dangerous and creates problems by itself. I’d rather rely on flatpak/appimages, but open for counter arguments.

So much this! As a user of both Arch and Gentoo I say, don't use Arch as Gentoo! It's not Gentoo! AUR is not a standard repository and there's a reason they make you jump through hoops just to use the thing.

Also, it's a total pain when normal package management is quick and easy. The building alone is weird in Arch and somehow like 60% of the crap I try to build from AUR fails hard and I just can't be bothered to spend more than like twenty minutes tweaking on it. Gr. 😅

(Aaalllsooo, apparently lots of people break their Arch installs using the AUR like it's a normal repo and then wonder why Arch is so crap and leave.)

I use Crystal Linux, which is Arch based.

I’ve tried Mint along with 10 other distros. What I liked about Arch is:

• Latest Kernel, always. This means new drivers, better support for your current devices and support for more devices. Security & performance patches.
• AUR. Massive repo of user submitted apps & libs most not found elsewhere.
• Arch WiKi. Everything you will need or want to do somebody else already did and documented it so everyone else can have a guide to do it. Best documentation site ever.
• Arch Repo. Always the latest Software. Officially maintained apps and libs land first on Arch, Debian & Ubuntu derivatives take ages to catch up in comparison.

It’s great having so much software available but the AUR makes me nervous because you really don’t know who you’re trusting when you install something from there.

FreeBooteR69 , 11 months ago

That's why you are supposed to check the pkgbuild before installing anything from the aur.

warmaster , 11 months ago

Flathub has hundreds of apps which are not sandboxed and untrustworthy. So, no source is safe, and even most “safe” apps are not protected from supply chain attacks. So, you always have to be careful. But I agree there are certainly degrees of safety, and the AUR is certainly another one, which should not be taken lightly.

Arch and Gentoo have IMO the best documentation ever and you learn a lot when you try using either of those distributions as you have to do everything from scratch starting from a minimal system. Since you’re saying you’re new to Linux though, I’d say you should start with something more user-friendly like Mint or Ubuntu (or even Manjaro if you want a rolling release distro) and stay away from Arch and Gentoo in the beginning.

Oh also who wants to play guess what’s in those directories ? It’s gotta be mostly music with that three level structure and size distribution

I run Openmediavault and I backup using BorgBackup. Super easy to setup, use, and modify

That would be really awesome! Especially if it could learn your preferences automatically by how you change the default arrangement.

SethranKada , 11 months ago in How do you all go about backing up your data, on Linux?

I use Pika backup, which uses borg backup under the hood. It’s pretty good, with amazing documentation. Main issue I have with it is its really finicky and is kind of a pain to setup, even if it “just works” after that.

nikodunk , 11 months ago

Can you restore from it? That’s the part I’ve always struggled with?

SethranKada , 11 months ago

The way pika backup handles it, it loads the backup as a folder you can browse. I’ve used it a few times when hopping distros to copy and paste stuff from my home folder. Not very elegant, but it works and is very intuitive, even if I wish I could just hit a button and reset everything to the snapshot.

Oh man, you brought back memories. Memories of when Ubuntu was awesome.

happyhippo , 11 months ago in How do you all go about backing up your data, on Linux?

Vorta + borgbase

The yearly subscription is cheap and fits my storage needs by quite some margin. Gives me peace of mind to have an off-site back up.

I also store my documents on Google Drive.

style99 , 11 months ago in Apt, packages kept back: why and how to resolve it?

nVidia drivers are a serious pain. You could brick your system if you aren't careful.

wildbus8979 , 11 months ago

Brick is a big word. Nothing that can’t be fix by booting a rescue image and chrooting into your OS.

gabriele97 OP , 11 months ago

You say that because they are listed as removable? If so because I updated from 515 to 525 months ago and today from 525 to 535. I think they are still there but are not used anymore and are safe

wmassingham , 11 months ago

At most I think you’d have to blacklist the module from loading at boot time.

melroy , 11 months ago

you can always run: rmmod nvidia and rmod nouveau. And then buy an AMD videocard. This works always! Thank me later!

thelastknowngod , 11 months ago in Ubuntu on Nuc Network Access

I cannot connect via VNC or see the folders from other devices.

Troubleshooting literally anything with computers requires logs, error messages, description of current behavior (ideally with expected behavior), and a background of what other devices/systems/OSes/etc are involved.

Posts like this that basically say “it doesn’t work” with no additional context will NEVER get you any help because no one knows what problem you are seeing.

“I’m running X os, version Y. I’m trying to do Z. The error message i am seeing in the logs for $SERVICE is ‘FATAL: Unable to do $TASK’. I tried to do this but I’m still not seeing the expected behavior.”

^^ This is how you get someone to help you.

Which ubuntu had this boot screen?

kool_newt , 11 months ago in How do you all go about backing up your data, on Linux?

I made my own bash script that uses rsync. I stopped using Github so here’s a paste lol.

I define the backups like this, first item is source, other items on that line are it’s exclusions.

Anticorp , 11 months ago in What distribution is most used in production environment

At this point? Probably Cent OS, since that’s what AWS uses. It’s a variation of Ubuntu. So if you don’t count it as separate, then definitely Ubuntu.

karlthemailman , 11 months ago

Are you sure you mean centos? Centos is a rolling release of the next version of rhel.

vanderbilt , 11 months ago

Amazon Linux 2 uses a mix of stream and Fedora IIRC.

SeeJayEmm , 11 months ago

CentOS is an RHEL variant, not Ubuntu.
