Can't run Etcher because it doesn't load an existing library

I’m trying Etcher for the first time, with the eventual goal of repairing a broken installation of my OS (which you should keep in mind). When I attempt to execute ./balenaEtcher-1.5.80-ia32.AppImage I get error while loading shared libraries: cannot open shared object file: No such file or directory. The file exists:

$ ll `locate`
lrwxrwxrwx 1 root root     36 Sep 25  2017 /usr/lib/x86_64-linux-gnu/ -> /lib/x86_64-linux-gnu/
lrwxrwxrwx 1 root root     14 Sep 25  2017 /usr/lib/x86_64-linux-gnu/ ->
-rw-r--r-- 1 root root 121280 Sep 25  2017 /usr/lib/x86_64-linux-gnu/

I’ve checked that it should be loaded,

$ sudo cat /etc/ 
# Multiarch support

and I’ve also set LD_LIBRARY_PATH, even though that’s “bad”.

Any further suggestions?

Hi there, it looks like you are on a 64bit OS, can you try balenaEtcher-1.5.80-x64.AppImage instead please?
