How to report crashes of Linux desktop client

I am running Nextcloud client on my Xubuntu 18 computer. Usually the Nextcloud desktop client runs fine, but once in a while it crashes (details below). I am not yet sure how to reproduce the issue.

My question though: I installed app from the PPA [1]. Because its a ‘third party’ package on Ubuntu, the standard crash reporter refuses to upload the crash image to Lunchpad etc.

What is the recommended/proper way to share the crash images with developers.I would like to help Nextcloud better :slight_smile:

nextcloud_error_1 nextcloud_error_2

Best regards
