Komga on Linux Mint will not start since last update (1.15.1)

[most-likely-2b]

Steps to reproduce

1.) Re-install Komga Linux version 1.15.1 from komga website on Linux Mint 22.
2.) Run application.
3.) Try to access existing server via IP address and port number.

Expected behavior

The application should start in the system tray and the server should be accessible in the web browser.

Actual behavior

Application will not start, and trying to access server in web browser results in an "Unable" to connect page (Firefox).

I have the same issue on my server running Mint. I made a copy of the database.sqlite file so I didn't have to rescan and set up everything again (found in /home/USER/.komga), uninstalled and then reinstalled version 1.14.1 using the below command the command line. I took them from the official download page and just changed the version numbers so it pointed to a previous one.

CPU=$(dpkg --print-architecture)
wget https://download.komga.org/debian/gotson-komga_1.14.1_${CPU}.deb
sudo apt install ./gotson-komga_1.14.1_${CPU}.deb

It's not a fix but at least you'll be able to keep using it until Gotson is able to get around to making any changes, but I would assume they're taking a well deserved break for Christmas and new year

[gotson]

the logs show that the app is started and running, nothing unusual

[most-likely-2b]

What do you recommend my next steps should be? The application is still not starting and I still can't access my server in the browser.

[most-likely-2b]

As posted above by Merkulese, rolling back to version 1.14.1 has fixed the behaviour, so I can confirm that something in versions 1.15.0 and beyond is causing this issue.

[aqiarch27]

I am also having the issue. Linux Mint 21.3
Rolling back to 1.14.1 worked for a while but then komga updated automatically and stopped working again. Application does not start in system tray and is not accessible through browser.

the application does start, the logs say so.

but then komga updated automatically

Komga does not auto update on Linux, you probably updated using apt

[Merkulese]

I've got some info that might help point us in the right direction: As Gotson and the logs show, the app does start but in my observations using system monitor (task manager) I can see when it loads up, uses resources and then after a minute or two reduces all resource usage to nothing and then closes. Unfortunately I've not been able to find out exactly why it happens but it does so every time the app is started. For updating, the latest version of komga appears in the update manager and the issue only started on my server after updating to 1.15.1. I tried rolling back to 1.15.0 but that also had the same issue of the app opening and then auto-closing after a short time.

I've just seen the 1.16.0 update and haven't tested it yet but will check at some point in the next day or so and feedback the results here

[Merkulese]

Issue remains on 1.16.0. app runs for a moment and then auto-closes so I've rolled back to 1.14.1 again

[Merkulese]

Tested a clean install of version 1.17 and am getting the same result. I've put the log below but the only thing I can see in it that might be relevant is a task rejected exception which leads to an eventual shut down

The reason it doesn't work anymore is because jdk removed system tray support for systems below gnome 45 openjdk/jdk#17860
UNIXToolkit.java#L236
This was backported to all previous jdk major versions so downgrading jdk isn't a good option
From my tests Mint 22 this still has this issue and tray icon is displayed in top left of the desktop instead of proper place in bottom right panel

Since Cinnamon (don't know if MATE is affected) is based on GNOME there are some environment variables that were used to detect it as GNOME
if GNOME_DESKTOP_SESSION_ID variable is set then the code path will treat it as GNOME desktop UNIXToolkit.java#L113
Then it'll try to execute gnome-shell command to detect version but will fail since there's no such executable on Cinnamon, and that is treated as unsupported version UNIXToolkit.java#L261
As a workaround you can unset GNOME_DESKTOP_SESSION_ID environment variable when you launch komga and this will bypass the detection
env -u GNOME_DESKTOP_SESSION_ID komga

I updated my Komga running on Mint 21.3 yesterday and am unfortunately running into the same issue now.

As a workaround you can unset GNOME_DESKTOP_SESSION_ID environment variable when you launch komga and this will bypass the detection
env -u GNOME_DESKTOP_SESSION_ID komga

Note that this workaround will cause PDF files to no longer load/render. See #1834
