Jabref 5.12 does not see several disks on Linux

I am working on a Ubuntu workstation with several disks. Jabref is only able to open files on the main disks, but not on others disks. A old Jabref (3.8.2) is able to see all disks and to open files on each disk.
Is it a bug or can I change a parameter?

Could you provide screenshots? What version of Ubuntu exactly?

I attached a pdf file with two screenshots

The left figure corresponds to the window (File/Open) with Jabref 3.8.2 and the right figure with Jabref 5.12

data and data2 appears in Jabref 3.8.2 (in yellow on the figure) but not with Jabref 5.12

the file system is displayed below with df command

the Ubuntu version is 23.10, but I believe that it is not associated to the distribution number.

Not only Jabref works correctly with Ubuntu, but also all others applications.

Did you have the snap version installed? This might be the case
You could try to install the deb version or try the portable with dpkg -i from terminal, otherwise you still might end up with the snap version

Solved! Thanks you!

I do not understand why the snap installation gives this bug.

The Jabref version is the same in both cases!

The snap version is sandboxed/more restricted by the OS

They are not the same. Snap, like Flatpak is more sandboxed (thereby more secure) than simple deb packages, but at the same time it comes with a tradeoff in usability.

See for example
