usr/bin/appstreamcli: symbol lookup error: /usr/lib/x86_64-linux-gnu/libsoup-2.4.so.1: undefined symbol: g_file_info_get_modification_date_time

Hello, you've been helping me on Twitter and I've got the other problems fixed (I'm pretty sure) after upgrading to 20.04 , but I have a new error in appstreamcli when using the appimagetool trying to compile my project.

Error:

This looks like an AppImage bug - apparently a different version of libsoup is used at runtime compared to what AppStream was compiled with (likely appimagetool messes with LD_LIBRARY_PATH and doesn't reset that when calling appstreamcli). Maybe @probonopd knows more.

Ok thanks and sorry to bother with this.

Try appimagetool from https://github.com/probonopd/go-appimage. It is not exporting LD_LIBRARY_PATH anymore.
