Maybe related to #123?
Maybe related to #393?

I don't have this behaviour with 20.04 and https://download.kiwix.org/release/kiwix-desktop/kiwix-desktop_x86_64_2.0.3.appimage. Closing the issue.

Reopening the issue, because it happens again with Ubuntu 20.04 and the Debian package in our PPA:

$ kiwix-desktop 
Library directory : "/home/kelson/.local/share/kiwix"
Compiled with Qt Version  5.12.8
Runtime Qt Version  5.12.8
aria2 tellActive failed : Invalid return code from ariaaria2 tellWaiting failed : Invalid return code from ariaadd widget
terminate called after throwing an instance of 'std::runtime_error'
  what():  Invalid return code from aria
Aborted (core dumped)

But it works with the latest appimage https://download.kiwix.org/release/kiwix-desktop/kiwix-desktop_x86_64_2.0.4.appimage

@mgautierfr This might be related to Qt as the appimage uses Qt 5.9 and the deb package 5.12.

aria2 tellActive failed : Invalid return code from ariaaria2 tellWaiting failed : Invalid return code from ariaadd widget
terminate called after throwing an instance of 'std::runtime_error'
what(): Invalid return code from aria

It is probably a problem with aria interaction and the debian packaging.

Probably a duplicate of #514
