New to Linux

[tech3475]

I just tried this on my Mint install, all I did was give it executable permissions and ran it from the terminal just fine.

Something else must be at play.

Edit:
It's a fairly old install of 22 and only FF was installed. I also had those errors OP had in the previous post.

So, I just tried to install qt library using this method

sudo apt install --install-recommends qtcreator
sudo apt install build-essential libgl1-mesa-dev

I then tried to install Citron, using the appimage.
Again, nothing happened, and when dragging it onto terminal, I still get these same error

QCoreApplication::applicationDirPath: Please instantiate the QApplication object first
QCoreApplication::applicationDirPath: Please instantiate the QApplication object first

No idea honestly, never used Citron myself and never encountered this error as far as I could remember.

Maybe something else is missing from the Citron setup itself?

In the meantime, good luck googling around and see what this could be, it could very well be something stupid that could be fixed in 2 seconds, I speak from experience, lol

Do you have QT libraries installed, by any chance?

I haven't used them that much, but isn't the point of appimage, etc. that they include all the necessary libraries?

I always see appimage as .exe sort of equivalent, I don't know what else is involved.

Anyway @Noctosphere I looked a bit around and clearly it's most likely just missing QT libraries.

Make sure to install every LibQt whatever packages you could find, most of the time they come as prerequisite for other things so you might just eventually get everything simply by installing more stuff from the Software Appstore.

You probably will bump into all the required libraries by installing a bunch of stuff also using Qt like Dolphin Emulator.

Just throwing ideas around, you never know what could work just by having more stuff installed in the process.

I'm not convinced this is the issue, as I said I had a vanilla install with just FF signed in and last updated everything months ago.

If OP missing these libraries is the issue then I think something else is at play.

I also had some QT errors in the terminal.

Yea, I don't know which one exactly I should install. I'm trying to follow online tutorials, but I feel like I'm just doing "trial and error" over and over again, and that I'm starting to mess with stuff I shouldn't mess with.
I just tried yet another method to install Qt stuff, and got this error message now
E: Sub-process /usr/bin/dpkg returned an error code (1)

I guess I'll just proceed to install Linux Pop_Os, but I just need to be sure of one thing. I currently have 3 OSes on my PC
When I booted up my PC earlier, I saw Windows Boot Manager, Linux Mint Cinammon and another Linux (Zara, IIRC)
Did I do something wrong when installing Linux (+uninstalling Windows, because I thought I did uninstall it)?

Can I just confirm:
1) was it an online connected install?
2) If you have a Nvidia GPU, did you install the latest recommended driver
3) did you update the system

 

[Exidous]

I have a tangential question (and I'm sorry if I sound like a dick).

and for the past week, TrueNAS

So, uh, how's that going?

I've self-deterred into planning Proxmox for my NAS because the received wisdom I've been getting is don't make TrueNAS your first dip into Linux.

Granted, I'm less brave than you (Win 10 IoT LTSC for another decade I guess?). But even after the hump of planning hardware for zfs, running TrueNAS just looks like a nightmare for a Linux virgin.

I also had some QT errors in the terminal.

What I was saying is that it's most likely just something missing that could be solved in a few minutes by installing more packages unless we know what it might be.

The other plausible option is that build of Citron is broken and could be discarded if it is the reason for the error to pop up.

Again, it's just me making suppositions since I have no idea what is truly in that computer, and not having it in front of me makes it harder to provide more helpful advices than that.

The only benefit from my suggestion at least is that the more things that get installed, the most likely more things will work since those libraries will then be present for everything else.
Basically, install stuff once and forget about it kind of idea.

On my computer I have well over 1000 packages installed and maybe half of this number is libraries and random packages that were required once for a very specific purpose, but now it's permanently there so it saves me time for anything else that might also require them installed.

Just sharing thoughts based on personal experience, really.
In fact, this sort of situation is also common on Windows for pretty much the same reason, so it's a perfectly reasonable assumption to expect similar outcomes on different computers.

1) yes
2) I remember there was "another recomemnded" option, like "open option" or something (It had the word open in it, but it wasn't "open source"). I chose the one labeled "Recommended"
3) No idea. I did restart it a couple of times for updates, but was it for Mint itself? No idea.

I've installed TrueNAS, had a couple of tweaking to do, but much less than for my main PC. Right now, it's running and I barely ever touch it (except to add torrents and/or medias to my Plex). As long as it's working, there's no need to tweak it again (Engineer rule #1 : If it's not broken, don't fix it)

Yeah I know that feeling, don't worry I'm sure you will eventually figure it out, I know you're smart

Probably not, but sometime Bootloaders keep leftovers from previous stuff installed, so you can just ignore those for now.
If you know how to edit Bootloaders options, then go for it and remove what you know is not supposed to be there.
Assuming you use UEFI from the BIOS or something similar, this is pretty easy to manage from BIOS depending on the way it is being set up for your OS installations.

Short answer: don't worry about it for now.

My point is that I have a barely used install which ran it just fine.

If there's an issue running this on their system then it could be a sign that something else is wrong with the install or they need to do something else

I also experienced errors which they did but again the software ran.

Besides, it looks like the depencies should be in the appimage:

Try running software updater to make sure everything is up to date.

Fair enough, again I have no idea either what is wrong right now so yeah.

 

[Noctosphere]

So, hum... I just downloaded all qt libraries, but when trying to install them, it's been error after error...

First, since cmake couldn't be found, I did as they asked, which was sudo apt install cmake
But then, since I got a "dependancies unmet" error, I did the other command they asked, which is apt --fix-broken install
But then, I get this other error, saying that the process had been killed by the signal (broken pipe)

So yea, definitly something wrong with my install

Well, it's 1:03 AM, it seems like PopOS just gets worse and worse too

my GPU is undetected (even if my monitor is plugged in it).
The max resolution I had was 1280x720 60hz on a 1080p 240hz monitor
After rebooting my PC, it was unable to get past the bios (which made me panick a bit), but managed to boot an old kernel
But now, my max resolution is 1024x768 (4:3 on 16:9 monitor is ugly)

I think I'll go to sleep before trying something else again. Good night

What does Pop identify your GPU as?

IIRC the latest version of Pop OS is a tad old and may not support the drivers needed for the 5060 out of the box. Also did you made sure secure boot was off?

 

[Kioku]

For me it was just fine, what where you running on it? As in hardware wise?

Just tried to install Fedora 43 fresh a week ago, and it was an absolute mess. 9800x3D paired with an RTX 4080. Known crash at the timezone screen when using the open source nvidia drivers (default btw). After finally settling in, there were other crashes and hang ups (it’s the latest version, sure, but cmon, they had betas). Said screw it and went back to Fedora 42. Same exact freeze on the setup as noted before. After I got that all ironed out, it’s been working relatively fine. However, that’s not an experience someone new to Linux should expect or be prone to experience. Hopefully, they iron out these issues quickly. I’d like to go back to 43.

I’m not new to the world of Linux and its shenanigans, but I’m far from what would be considered an advanced users. This was moving from EndeavourOS.. May try Cachy next.

Yea, that's what I was told, that it was no longer supported, yet, people here told me "it is still supported". Anyway, I'm back to mint now

Ah fuck, Nvidia drivers. Ughhhhhhhhhhhhhhhhhhhh.

Yeah I had a solid experience because I had an amd GPU. I just wished Nvidia would stop, dropping, the godamn fucking ball. I used to have a rtx 2060. And Linux felt like I was pulling teeth out. This was before Nvidia started fixing their shit.

Literally everything worked as it should from the word go on my amd gpu. The only issue I ever had, was some non critical background service that would crash at boot up, that I just didn't take the time to look into. (For fedora specifically)

And heaven forbid you have a Nvidia Optimus laptop. Good fucking luck getting shit to not glitch out on Wayland, because you'll need it with that kind of laptop.

So, hum, I still don't have access to my video games on Steam. When I launch them, they start compiling Vulkan sharders, then syncing to steam cloud, then "start launching" and nothing happens.
Any ideas?

You can diagnose Steam games in a few ways.

If it's a Windows game, set this in your launch options, and a log (e.g. steam-420.log) will appear in your home directory:
PROTON_LOG=1 %command%

If it's a native Linux game, set this in your launch options, and the same will happen (use any file name):
%command% > ~/game.log

You may also find Steam's console useful. If you want to make it available, either start Steam with -console, or run this:
steam://open/console

However, if you're having problems running games, chances are you're missing 32-bit libraries (which might not be necessary nowadays?), but as I don't use Linux Mint, I can't help much in figuring out what's missing.
