[RESOLVED] AppImage My downloaded appimage files no longer work

[Stefanso]

AppImage My downloaded appimage files no longer work. So what do I have to do now? I get a window that pops up and says Are you sure you trust this app and you want to execute? I click yes and nothing happens.

For some kinds of AppImage there's a sandboxing issue. I can run BitWarden and Balena Etcher with, f.ex.,

./Bitwarden.AppImage --no-sandbox

In any case, running the AppImage from a konsole might be informative.

TYVM jlittle so I ran terminal and here is the code response...I will upload an image if the system lets me:

"stefanso@Stefanso-Air:~$ ./Trezor.AppImage [1442961:1008/084809.275122:FATAL:setuid_sandbox_host.cc(158)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /tmp/.mount_TrezorfT7RjQ/chrome-sandbox is owned by root and has mode 4755. Trace/breakpoint trap (core dumped) "
so I ran w/ sudo:
"stefanso@Stefanso-Air:~$ sudo ./Trezor.AppImage [sudo] password for stefanso: [1008/085400.636261:FATAL:electron_main_delegate.cc(294)] Running as root without --no-sandbox is not supported. Se e https://crbug.com/638180. Trace/breakpoint trap"

Then I ran with the whole line ...--no-sandbox" and there it is. Sometimes I can be so DENSE in the head...DUH!

Then I ran with the whole line ...--no-sandbox" and there it is.

So, you ran:

sudo ./Trezor.AppImage --no-sandbox

Thanks for that tip. Was scratching my head trying to get Fontbase to run as I was working on a new design for a book cover in GIMP and wanted a new font. Got a set of designer fonts but they're just too much to install and remove each time manually. I know Fontbase works wonders back when I used Windows for Photoshop and Paintshop jobs. Trying to get adjusted with GIMP instead. Thanks again for that tip (the part with no sandbox via CLI).
