Open with/ drag and drop from mounted location not working (Permission error) #1126

Open atmelino opened 1 week ago

atmelino commented 1 week ago

Describe the bug

When I drag and drop a file that is on a mounted drive, for example a USB drive or a drive mounted via fstab, from the nautilus file manager into the pdfarranger window, nothing happens. The same behavior occurs when I try to use "Open with". If the file is on the Desktop, it works.

I narrowed the problem down to a permission error (see below)

To Reproduce

Steps to reproduce the behavior:

  1. Open nautilus
  2. Navigate to a mounted drive
  3. Right Click on PDF file and select Open with -> pdfarranger

or

  1. Open nautilus
  2. Navigate to a mounted drive
  3. Open pdfarranger
  4. Drag and drop PDF file from nautilus into pdfarranger

To monitor the error:

  1. Open terminal
  2. type "pdfarranger"
  3. Open nautilus
  4. Navigate to a mounted drive
  5. Drag and drop PDF file from nautilus into pdfarranger (or open with)

No error occurs when the PDF file is on the Desktop.

Expected behavior

Drag and drop file into pdfarranger window, expect file to be loaded

Input files

Any PDF file

You have 2 options,

Also, @atmelino can you confirm if this 24.04 installation of yours is a clean installation or updated from old installations?

atmelino commented 1 week ago

Didn't help:

sudo snap connect pdfarranger:removable-media causes error error: snap "pdfarranger" has no plug named "removable-media"

sudo apt install xdg-desktop-portal-gnome xdg-desktop-portal-gtk already installed, output: xdg-desktop-portal-gnome is already the newest version (46.2-0ubuntu1). xdg-desktop-portal-gtk is already the newest version (1.15.1-1build2). 0 upgraded, 0 newly installed, 0 to remove and 5 not upgraded.

This is on a newly installed Ubuntu 24.04, installed to an empty disk.

More information: This problem did not occur on previous version that were installed via sudo apt install. I have had similar problems with other snap installed programs.

Actually I also faced some problems today with home plug, may be what you can try is revert snapd, if it's there in your machine

sudo snap revert snapd

This is probably not something with this snap only. Also, try doing a restart, may be what else you can do is

sudo snap disconnect pdfarranger:home

And then try opening it

Could you please show us apparmor denials as listed by 

dmesg | grep DENIED

Thanks!

Thanks, is that all of them? From the ones I see here we can ignore all the snap-confine denials, those are known and caj eb ignored. I wonder what changed between versions though. Do you know if the app is using xdg portals for the folder access?

Yes this app uses xdg desktop portals. I guess he has already reverted the snapd snap.

zyga commented 1 week ago

I don't know what may be the problem then :/.

Can I ask the reporter to re-check with snapd snap using latest/edge channel:

sudo snap refresh snapd --edge

You can check if this worked by running snap version.

Thank you!

The problem was probably particularly in 2.65.3 release which was later reverted. I also faced some similar problems
