I'm experiencing the same issue with files mounted under /mnt/user/sshfs/user@server/home/user.... where user is the username of the individual and server is the server they are accessing. This means /mnt is also affected.
Removing the apparmor rules resolves the issue. I have to say I agree with the others here that these rules are inappropriate. What about if an application came with an office document as part of its documentation? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/1751005 Title: libreoffice cannot open a document not within $HOME Status in libreoffice package in Ubuntu: Opinion Bug description: Starting with today's update to LibreOffice 188.8.131.52 40m0(Build:1), files not within the user $HOME directory cannot be opened.
