Works as normal for me on both Debian Bookworm and Trixie.
Without knowing exactly what “No such file” it’s failing to find for you, it’s hard to say much more about what the actual problem you’re seeing is, other than betting the answer to that problem most likely is:
“It’s (already well past) time to update your distro again”…
Well that would be the first time ever for “appimage doesn’t start on my system” then…
So you tell us almost nothing about the system it didn’t work for you on, then get upset when an equally generic (and never before wrong) answer doesn’t solve it for you?
I gave you information you can use, it’s not broken for everyone - but we likewise don’t know what Federico is running, so it may or may not just be a problem with “5 hour old Manjaro”.
If you can’t tell us more than that, there is no cheat sheet at the back of the book we’re not telling you about, and insults for thanks isn’t motivating me to offer you more guesses that might also not instantly solve it.
We’ll just have to wait until someone with a broken system explores it enough that they can tell us what makes it broken.
