Thanks Static_Rocket! That change does the trick on my end.

I'm seeing exactly the same error as Alberto using both pikaur and makepkg. I have fuse2 and 3 installed, and I'm not editing the PKGBUILD. I can run the makepkg-downloaded AppImage directly without issues.

@AlbertoAru I'm unable to reproduce this issue with both yay and makepkg. Might it be related to the path you're using to build this package? It looks like it cannot find the file.

The URL you posted, is the same as the one used by the PKGBUILD, so the file downloaded should be the same.

If you're still unable to fix your issue. Please provide a bit more context on how to reproduce. (aur helper, path etc.)

This doesn't look like a squashfs image.

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 https://github.com/AppImage/AppImageKit/wiki/FUSE 
for more information
open dir error: No such file or directory

When using the --appimage-extract option:

This doesn't look like a squashfs image.
Failed to open squashfs image

I saw that if I directly download the AppImage from the source and manually execute it, it works fine

fuse2 should be added as a dependency, otherwise there can be an error:

"dlopen(): error loading libfuse.so.2"

Would recommend removing the following line as it attempts to break out of the packaging directory and make a dir that is unnecessary now that the udev rule is being properly installed under /usr/lib/udev/rules.d

You may also want to add fuse as a dependency as AppImages in general need it to function.

provides=('vial=${pkgver}') is bogous. The environment variable does not get evaluated because of single quotes (this is simple bash workings). You need to replace it with
provides=("vial=${pkgver}")
(double quotes).
Regards and thanks for maintaining!

Can you add vial=${pkgver} to the provides array and maybe also vial to the conflicts array?

Regards and thanks for maintaining.

@android Did you check if this same issue is present when using the regular appimage and not the aur package?
