Hello everyone,

I have installed ubooquity on a Synology NAS running as a Docker/Portainer application. I recently have discovered annoying HDD activity every 5-10 seconds or so all night long on the NAS and found out that this seems to come from Ubooquity.

With Iotop I have found the only HDD write acitivty seems to from:

Greetings All, I'm new user to Ubooquity, finding it very fascinating and matching my simple needs to read my books collection over browser if possible. to keep it simple, instead of raspberry pi, I'm using old i386 headless linux box with some SSD attached for plex and Ubooquity. Everything looks okay though when I try to login with any users I setup to read the books, it throws me back out to user-login screen. so can't see any books.

video capturing the behavior

Below are the logs and setup details.

EDIT

strange though I observed for some reason the scan doesn't reflect the books under 'added/updated' section but only under total.

I have created a keystore (JKS) and added my cert as pkcs12 with alias-name ubooq_key, as described in https://vaemendis.github.io/ubooquity-doc/pages/tutorials/lets-encrypt.html.

I added the keystore via the admin-page > Security.

When i hit save & restart, page reloads and tells me "Not connected to server".

The "normal" ubooquity-page wants to download a file "download", but the page doesnt show up.

So here my questions: Did i miss a relevant thing regarding the startup-options?

I am serving ubooquity via start-script (running inside a freebsd-jail).

My domain is ubooquity.home.lan.

Changes the port? Mine is set to 80 and 81 for /admin.

I tried with renaming the keystore from keystore to keystore.jks and ubooq_key and finally ubooq_key.jks, every time changing the settings too, restarted the ubooquity server and every time the same errors.

keytool -list shows the cert as valid.

I am running ubooquity 3.0.2.

Thanks very much for any help.

At the moment I am manually copying my database file after each scan but as the application locks the db I have to exit the server first.

What I would love is if before it starts a scan it creates a backup of the database. I envisioned a default of 2 backups and an option in the config to adjust that number upwards as well as changing the backup location. With backups either deleted or over written when it launches a scan based on the number of backups configured. Thanks

I have UBooquity 3 running during 5 or 6 days and after restart the machine i have this problem. Could you how can i recover the database?

Any browser running on an iOS device won’t update the bookmark/progress feature with the epubreader. I tested on iPad Mini 6, iPad Pro 2nd gen, and MacBook air. It seems to work fine on my Windows computers and Android phone. I think I traced it back to the event window.onbeforeunload in the epubreader.js. Researching it brings up that a number of browsers/systems don’t support/aren’t compatible with that event. I tested adding these:

document.addEventListener('visibilitychange', function() {
if (document.visibilityState === 'hidden') {
$scope.storeBookmark();
}
});

setInterval($scope.storeBookmark, 60000); // Save every 60 seconds

and it is now updating reading progress on epubs in the browser reader.
Hopefully this is helpful. Let me know if you need any help narrowing it down further or testing.

I have ubooquity 2 running during years and when i try to lunch version 3 i have this error:

Exception in thread "main" java.lang.UnsupportedClassVersionError: com/ubooquity/Launcher has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 52.0

My machine is a Windows 11 update 23H2. 

Then i stop ubooquity 2, try again a nothing.

My ubooquity 2 run commad is :

java -jar -Xms1g -Xmx2g g:\ubooquity\Ubooquity.jar --headless --remoteadmin

and this work for me perfectly during years.

The i try whith the same command and i have other error:

G:\Ubooquity 3>java -jar -Xms1g -Xmx2g Ubooquity.jar
Error occurred during initialization of VM
Could not reserve enough space for 2097152KB object heap

Then i upgrade java for the last version and now i have:

G:\Ubooquity 3>java -version
java version "1.8.0_411"
Java(TM) SE Runtime Environment (build 1.8.0_411-b09)
Java HotSpot(TM) Client VM (build 25.411-b09, mixed mode, sharing)

Restart the machine and again the same error.

Also try as administrator but the error continues.

I am using now since some months the 3.0.2 on freebsd 13 and encountered some problems with PDFs: Some of the newly imported pdfs dont show the title-page, only the white standard-symbol. When i try to open them i get a "Page not found".

Download works.

Here the logs:

I hope, that helps.

Ah, other error: When i click on the upper left ubooquity-symbol, it redirects to servername:2203; i have changed that ports to 80 for the library and 81 for admin. I have changed that value in the preferences-2.json as well, but no change in behaviour.

Edit: Some of the older pdfs show the same error; they were shown with their respect first page in the 2.1.2.

Thanks

I'm trying to install Ubooquity on Ubuntu 22.04.4 LTS with openjdk version 1.8.0_402.

I get this error:

 java.lang.NoClassDefFoundError: javafx/fxml/Initializable

which is:

     Caused by: java.lang.ClassNotFoundException: Failure to load: javafx.fxml.Initializable

From what I have read online, it is not possible to add JavaFX to OpenJava 8.

How should I proceed?

I have a number of pdf scans that seem to be having a compression or scan issue with Ubooquity3. I have a suspicion that it has to do with this error:

ERROR o.a.p.contentstream.PDFStreamEngine -  Cannot read JBIG2 image: jbig2-imageio is not installed

Is there anything I can do from my end to fix this issue on my PDF scans?

I'm torn between loving the new version of Ubooquity, but not being able to read a lot of my books due to this PDF scanning weirdness.
