PDF files won't open anymore

[j0hannes]

JabRef version 5.0-dev

• I have tested the latest development version from http://builds.jabref.org/master/ and the problem persists

Clicking on a document icon used to open the associated PDF. Now, the PDF viewer opens and closes immediately. No error is logged.

Steps to reproduce the behavior:

1. Click on a document icon

Cannot reproduce this under Windows 10. PDF opens fine. Sure the path is correct?

[j0hannes]

I have the configured a "main file directory". The "file" entries are just bare file names. If I go to that directory and call the PDF viewer with one of the file names, it will open.

Please check external programs tab in preferences where the paths to PDF viewer etc. are set.

There are two options under "Open PDF", Adobe Acrobat Reader and Sumatra Reader. None of them is checked. When I click on a document, I see a new instance of Okular, which is the default application that has worked until now. After a couple of seconds this instance disappears; no errors are logged.

[AEgit]

JabRef 5.0-dev
Linux 5.0.0-27-generic amd64
Java 1.8.0_222

Cannot confirm this issue. What I do note with the snap version I am using, however, is that every time I want to access a PDF file, I have to accept the following message:

Allow opening file?

Allow snap "jabref" to open file "/path/to/my/pdf/my.pdf"?

This dialogue will close automatically after 5 minutes of inactivity.

My PDFs are stored on a NTFS formatted drive (I am running Linux and Windows in a dual-boot configuration) which is mounted to /media/myuser. To access that folder using the snap version of JabRef it was necessary to use the removable-media option, i. e. sudo snap connect jabref:removable-media. This allows JabRef to access the drive/folder. However, the message reported above will still appear every time JabRef tries to open an associated file stored on the NTFS formatted drive. Is there a way so that I only have to accept this message once? Is this even a JabRef issue or is this something related to the general implementation of snap?

With the most recent dev snapshot (JabRef 5.0-dev--snapshot--2019-09-05--master--99a0a7a8d), PDF files open instantaneously. Have there been any recent changes on that code?

I think, we may close the ticket.

This behaviour is still present in the with the deb package in

https://builds.jabref.org/master/jabref_5.0.0-1_amd64.deb

Built in 2019-10-21

[j0hannes]

The same version from sources works for me.

[amontero90]

And by sources you mean.. exactly the same link I provide above?

I just tested again on a fresh installation of Kubuntu 19.10. The behaviour is exactly the one that j0hannes described in the first comment. I can also reproduce what AEgit described with the snap package even though my files are stored in the same unit as JabRef.

[j0hannes]

These are the sources: https://builds.jabref.org/master/JabRef-portable_linux.tar.gz

Shouldn't make a difference to what you find in the deb package, though.

[amontero90]

I should have said in my previous comment. The same behaviour with the sources you mentioned.
