ive followed the instructions here Ping Viewer to download the software on my linux machine, however double clicking it is not running the app and when i ./ the application i see this error /tmp/.mount_pingviwUKxTT/AppRun.wrapped: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34’ not found (required by /tmp/.mount_pingviwUKxTT/usr/bin/…/lib/libkrb5support.so.0)

Hi @axppxsky -
Are you running Ubuntu 22.04 or newer? We don’t support any older versions lower than 22.04. Thanks!
