Cannot mount AppImage, please check your fuse setup


Guys today I'd like to touch problem with AppImage. I'm not sure if it's right section (so please move it if I've marked it inccorrectly).

So I have read about AppImage files. I wasn't super happy to use it but I don't have other option.
In theory we download .AppImage files open it and it should run. In reality (at least my case) it ask for integration , which fails finally and that's why it ask one more time for extract all files and run it directly. So sure, what elese do I have..? After that again it can't handle and return following error:

Cannot mount AppImage, please check your fuse setup.
You might still be able to extract the contents of this AppImage
if you run it with the --appimage-extract option.
See FUSE · AppImage/AppImageKit Wiki · GitHub
for more information

In that part I have to admit that I have my temporar solution like this:

  1. downoload appimage file
    a) run with
./Ultimaker_Cura-4.13.1.AppImage --appimage-extract-and-run

Yeap, here is about Cura (slicer soft for 3d printing which my is my best choice). And please don't advice here me to install it from pacman etc. while pacman version is outdated and desn't cover a lots of things. Besides Ulimaker suggest their official Appimage iso. So that's bying said let's follow with that path.

That way run app behave perfectly fine and work great! No doubs about it.

b) next more convinet way is option where we can firstlu extract it :


This way I get :

c) the best option is just create a shutrcut link for run that particular app. So we have to edit

Desktop content in my case is :

[Desktop Entry]
GenericName=3D Printing Software
Comment=Cura converts 3D models into paths for a 3D printer. It prepares your print for maximum accuracy, minimum printing time and good reliability with many extra features that make your print come out great.
Exec=MESA_GL_VERSION_OVERRIDE=4.5 MESA_GLSL_VERSION_OVERRIDE=450 /home/zawier/CURA/squashfs-root/./AppRun

And setting up additional parameters :

I'm able to create pernament icon enywhere and it also works great.
That's my current solution.

But question is why standard AppImage files are not able tu run properly itself? Probably you suspect that's broken Cura version or something. Not at all. I have the same problem with that type of files always. No matter what app I'd like to fire up.

Can it be fixed somehow, that system knows from begining what it should to do and how?

I haven't found answer for that problem . That's why I've posted here.
What is your experience with that extention? Have you also noticed that behavior?

Best regards

Oh yeap, I've seen that post and aslo add

chmod +x /path/to/file
╭─[email protected] in ~ took 2s
╰─λ history | grep chmod
2022-02-22 01:29:10 chmod +x Cura_3.14.1.1.desktop
2022-02-22 01:26:49 chmod +x cura.desktop

With the same result. So It desn't answer my question. Even if adding mod before running.

Do you have fuse2 and fuse3 installed?

Yes, I do:
fuse2 - version 2.9.9-4
fuse3 - version 3.10.5-1

Do you have libappimage installed? Does Garuda Downloader work?

╰─λ pacman -Q libappimage
libappimage 1.0.4-1

I haven't installed Garuda Downoloader until now. Quick check and it look to work fine:

And you do have AppimageLauncher installed, right? I don't do any Appimages till I have that installed.

Of couse I do.

So the issue is with the AppImage you downloaded in that case, since Garuda's seems to work fine?

I'm affraid no, because iso was downloaded but once I've tried lunch flasher (real appimage) then

And one more time :

Oh you use an AppImage launcher? Ewwwww.

sudo pacman -R appimagelauncher
reboot (necessary!)
And then try again.

Appimagelauncher most likely isn't the issue. I get that message with Zoho Mail but it launches and runs without issue, and my other programs installed using Appimagelauncher just work without any error message.

Didn't help. The same case. Besides before I was able to run any appimages on my way. Currently I'm not. So that's why I've installed it one more time.

Did you do a reinstall or any major changes between AppImages working and not.

No issues with them on myside so its weird. I know you have fuse2 and fuse3 installed. I know it doesnt work with fuse3 so wondering if your system isnt picking up fuse2 for some reason.

Well, surprisingly no. I had that issue from begining, since first time tried run AppImage file. But then I was able to find workaround (which still works for me, but I'm just tired to always go that way. I'd like to work it as designed, straight out of the box).

Regarding a link, been there before. Only one usefull info is :

sudo chmod u+s `which fusermount`

Which unfortunatelly hasn't fixed a problem.

I've been researching your issue and everything points to an issue with FUSE. Usually if a person needs to extra an appimage its because FUSE isn't working.

I suspect that FUSE might be installed but isn't loaded into the kernel as a module.

If you do a lsmod in the terminal does it show that fuse has been loaded?

Yep, here it is:

Please try running

sudo modprobe fuse

Then see if your app opens

Also are you trying to run the images from your home folder?

Done it long time ago, but checked it one more time - the same error, sorry.

It doesn't matter which location it is run from. Current tried from /home/zawier/Applications/ but also /home doesn't work.
