Etcher appimage not working in Ubuntu20.04

Doubling clicking the appimage did not work so I tried the following commands

chmod +x .appimage
sudo ./.appimage

but it gives me the error

dlopen(): error loading libfuse.so.2

AppImages require FUSE to run. 
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

but Fuse is installed in my system.

apt-cache policy libfuse2
libfuse2:
  Installed: 2.9.9-3
  Candidate: 2.9.9-3
  Version table:
 *** 2.9.9-3 500
        500 http://mirror.xeonbd.com/ubuntu-archive focal/main amd64 Packages
        100 /var/lib/dpkg/status

I'm on Ubuntu 20.04

Solution 1:

According to the corresponding issue the downloaded Appimage file is a 32-bit version

balenaEtcher-1.5.121-ia32

while the installed library is 64-bit

apt-cache policy libfuse2
...
        500 http://mirror.xeonbd.com/ubuntu-archive focal/main amd64 Packages

Unfortunately the error message from the Appimage code is insufficient:

dlopen(): error loading libfuse.so.2

AppImages require FUSE to run.
...

It doesn't tell what version of the library the dlopen() call searched for or where it searched for the library. This is a bit confusing when you see that the library libfuse.so.2 is installed on your system, contrary to the error message.

Running the Appimage with strace might show that it searches for the library in directories for 32-bit libraries.

So in case of this error you should check if the architecture of the Appimage file matches your system's architecture.
