Calibre Window quickly disappears (1 second after splash screen)

Calibre Window quickly disappears (1 second after splash screen)
Is there a way to reset all change made to calibre settings via terminal?
I can't use Calibre Library anymore. It won't start properly: its window (the blank one - after splash screen) disappears very shortly after it gets loaded.
What might caused this:
I changed port 8080 on server settings to 80 and enabled automatic startup of server.
Note that calibre restarted without letting me apply settings...

I uninstall and reinstall it several times but the problem persists.


"calibre-debug -g" output this:

As far as I know, only applications running as root can open ports less than 1024; so presumably you will need to run calibre as root and correct that port assignment.

[Delly15]

Thanks PeterT for your quick reply. Calibre does work when I run it as root. But I can't correct the port assignment because I see that it's on 8080 (the default).

When I run it as normal user, the problem is still there.

You need to remove the disto version of calibre then go to the official calibre web page and install the latest version of calibre.
calibre is up to version 2.32 and you are on 1.25.
Download for linux
One thing to try is to rename .config/calibre then restart if calibre starts it will be as if it is a new install.

You will manually have to edit the configuration file. I'm not sure where it is located under linux, but you are looking for a file called server.py. In this file you will find the following lines

### Begin group: DEFAULT
 
# port
# The port on which to listen. Default is 8080
port = 80

Change this back to 8080.

More than likely this is stored in a hidden directory within your home directory.

(And no need to revert to the non distro version).

Located at:

/home/yourusername/.config/calibre/server.py

And yes it is recommend to not uses the distro version.

While it might be recommended it should be noted that this issue would also happen with the official version.

Thanks for your support. I edit server.py and calibre works again.
I will install official version 2.32...

Make backups of your library, and .config/calibre folders first.

Then remove the distro version then install latests version. The 2.32.1 version will use your present .config folder and library. You will find many updates and improvements. The distro version is about two years and over fifty updates out of date.

Backup, backup, backup.

luck
