I recently had to reinstall my system (openSUSE Tumbleweed), and I'm experiencing some problems to run AppImage applications.

In particular, they are FontBase and Gravit Designer; the files are of course marked as executables, and are placed in a folder in my /home

They were perfectly running before the system re-installation, but now I can't get them to run; when trying to start them from CLI, I get the following error

GravitDesigner.AppImage: GravitDesigner.AppImage: cannot execute binary file

I've also tried to run them with sudo, with the same results.

How can I solve this?


I was able to run them again by changing permissions to fusermount binary, by running these commands as root:

chmod a+x /usr/bin/fusermount
chown root /usr/bin/fusermount
chmod u+s /usr/bin/fusermount

Source, on AppImage forum


This is a known issue with the default permissions for FUSE in openSUSE Tumbleweed reported in May: https://bugzilla.suse.com/show_bug.cgi?id=1041159

Please check that bug report for updates.


Please do:

  1. file ./GravitDesigner.AppImage (does it say "(...) ELF 64-bit LSB executable, x86-64 (...)"?)
  2. uname -p (does it say "x86_64"?)
  3. chmod +x ./GravitDesigner.AppImage
  4. ./GravitDesigner.AppImage

If that fails, please re-download and try again. If that still fails, try with a different Linux installation (Live CD).

  • Like I wrote in my question, the apps were working before the system reinstall, it is not a problem of different architecture, and, like I said, they are set as executables; they are also residing in my home, so they were not changed, redownloading or trying them on another system is not going to help: it happens with all AppImage files, it is a problem related to my system, not to one of the executables. – Sekhemty Oct 4 '17 at 19:15
