Firefox Snap Testing 2021-2022

My Downloads folder is directly under my home directory.

I now realise that the failure only occurs on certain links. The one I found it on is .

https://sourceforge.net/projects/openofficeorg.mirror/files/4.1.13/binaries/en-GB/Apache_OpenOffice_4.1.13_Linux_x86-64_install-rpm_en-GB.tar.gz/download

As you can see this points at SourceForge. The link itself is from here
https://www.openoffice.org/download/.

The failure causes apparmor to record to following denials in /var/log/kern/log.

Downloads that do work do not generate any apparmor denials. I am unsure whether the kuditd_printf_skb message has any relevance.
