Description Tomas Lipensky 2018-03-09 15:24:02 UTC 
Description:
I'm able to browse mounted encfs mountpoints and open any document by LibreOffice 5.4.4 and lower. In version 5.4.5 no file can be open in encfs filesyste, browsing of encfs directories works.
In version 6.0.0 even the browsing is impossible.

I'm on Ubuntu 16.04.4 LTS, kernel 4.13.0-36-generic
encfs version: 1.8.1-3  amd64

Impacting Writer, Impress, Calc, I didn't test other components

Steps to Reproduce:
1. Install LibreOffice 5.4.5 or 6.0.0 on Ubuntu
2. install encfs, create and mount encfs FS to directry, for example /mnt/encfs
3. copy any document there
4. try to open the document by Libreoffice (writer, ...)
3a. alternatively "save as" any documet by libreoffice to /mnt/encfs

Actual Results:  
Error that the file is not readable (rights are OK, i can access it any other program, mainly by older version of LibreOffice)

Expected Results:
LibreOffice can handle the encfs mounted filesystems and files there


Reproducible: Always


User Profile Reset: Yes

No error here when accessing documents from an encfs mount point with LO 5.4.5.1 / Ubuntu 17.10.

Note that there was an issue related to AppArmor in some downstream releases, ie. read bug 98776 comment 40.

I think that only affected 17.10, though.

It's worth a shot trying with an appimage: https://www.libreoffice.org/download/appimage

Thank you for your feedback and advice. It really works.

It means it must be a combination of OS libraries (in Ubuntu 16.04) and LibreOffice (LO) version, like LO in older version calls an one object in OS library which works with OS, LO in new version calls different object OS libraries which has a bug. In case of AppImage the different object is embedded in the AppImage. Do I understand well? Or maybe some older part of LO stays installed and used by new LO?

Yep, something like that. Let's close.
