Thumbnails are not displayed also for recently created or moved images in jpg, .png and .gif format.
On a directory (Pictures) i have some .PDF, .gif, .png and .jpg (images of which I see the thumbnails)
I copy the images to a different directory (Documents) and thumbnail are not correctly displayed

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Jane Atkinson (irihapeti)]

Not seeing thumbnails of images and pdf in VM install.

[Adam Reviczky (reviczky)]

Not sure if this is fixed in 45.2, but gdk-pixbuf-thumbnailer and evince-thumbnailer do generate the correct thumbnails.

NOT fixed with 45.2

see for an apparmor workaround: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/2054183

[Adam Reviczky (reviczky)]

possibly related to: https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/2046477

[Sebastien Bacher (seb128)]

it seems another fallout from the new apparmor restriction described in bug #2046844 and probably a conflict with the sandboxing in https://gitlab.gnome.org/GNOME/gnome-desktop/-/blob/master/libgnome-desktop/gnome-desktop-thumbnail-script.c

[Dmitry (ru-77)]

The same problem. Neither photo nor video icons are created.

[Georgia Garcia (georgiag)]

This issue should be fixed by apparmor 4.0.0~beta2-0ubuntu3 which is currently in -proposed

[corrado venturini (corradoventu)]

Installed apparmor from proposed: problem solved.
Thanks

[corrado venturini (corradoventu)]

On a new install from Ubuntu 24.04 LTS "Noble Numbat" - Daily amd64 (20240322) the problem reappeared

[Sebastien Bacher (seb128)]

did you install the proposed version again? because the update didn't make it to the release pocket yet so it's not part of the ISO/standard installation

[corrado venturini (corradoventu)]

NO, this is a fresh install w NO proposed enabled, but post from John.johansen says 'Fix released'
Also bug status says 'Fix released'

And why this message about 'ubuntu.sources.curtin.old' ?

[corrado venturini (corradoventu)]

Still same problem on a fresh install from Ubuntu 24.04 LTS "Noble Numbat" - Daily amd64 (20240324)

problem does not disappear deleting .cache/thumbnails/fail

[Sebastien Bacher (seb128)]

there is need to keep adding new comments, that bug has a fix available which is blocked in proposed, it doesn't need new information or confirmation that it is broken while the fixed version didn't land in the release pocket

[corrado venturini (corradoventu)]

Usually 'Fix Released' means RELEASED, when the fix is blocked in proposed the status is 'Fix Committed' so 'Fix Released' is confusing.

[Sebastien Bacher (seb128)]

I've changed it to fix commited now

[corrado venturini (corradoventu)]

Thank a lot, I laboriously convinced a friend to use Ubuntu and it was difficult for me to explain that Released was not RELEASED

[corrado venturini (corradoventu)]

Nautilus not changed but problem disappeared after last updates

[Sebastien Bacher (seb128)]

The fix was in the apparmor package and not nautilus and that is included in your updates list indeed, the fixed version finally migrated out of the proposed pocket
