Calibre 5.7.2 Hangs When Restarted In Debug Mode

baslow · 12-13-2020, 05:04 PM

I am running Calibre 5.7.2 in Ubuntu 20.10.

In order to diagnose a problem with the DeDRM plugin I have tried, multiple times, to reboot in debug mode, both from the menu and by using Shift+Ctl+R. Each time, the program hangs. Nothing is clickable and when I minimize the window I see the box that reads "Starting up, please wait...Initializing user interface".

I end up having to kill the process.

Anyone else experiencing this? Any ideas?

UPDATE:
After killing the process, I do get this log, which doesn't seem to me to shed any light:

Since you have Calibre 5.7.2, go download and install the DeDRM v7.0.0b4 plugin.

Thank you.

Your debug should look a lot like this:

Spoiler:

You seem to be having a problem with your database or HD.

I recommend you rename your library folder then start calibre--it will start with a new empty library--then change to your old library and run library maintenance on it.

P.S. I have no problems with DeDRM

Thanks.
There may be problems with my database or HD but the "startup time" seems to be a reflection of how long I wait before I kill the process; the debug window pops up immediately AFTER I kill the process and shows a startup time roughly equal to how quickly I let Calibre run before doing so.

Seems I need to learn more about posting to this forum; timed out trying to update my incomplete previous post.

It is debug mode, not DeDRM, that I meant to be asking about.

The DRM plugin I've been running was loaded from a file downloaded recently, DeDRM_plugin_7.0.0b4.zip. It has mostly worked but I was trying to investigate its failure with a specific book -- AZW3, purchased from Amazon for my Kindle Paperwhite. Apprentice Alf recommends removing the book, running Calibre in debug mode, and then adding the book again to generate a verbose record.

My problem is not with the general operation of Calibre, which runs fine in regular mode so far. I've renamed the library, started over, run a library maintenance check and found nothing.

So, to be clearer than I was before: Is anyone experiencing difficulties running Calibre 5.7.2 in debug mode?

It did that for me too, many versions ago. I have no idea what triggers it, as it hasn't been doing it for quite a while now.

Ok I just upgraded to calibre 5.7.2 and ran debug from a cold start no problems.

Spoiler:

Recommendations:
Down grade calibre to 5.6.0--using the Reverting to a previous version instructions at https://calibre-ebook.com/download_linux
run calibre in debug see if that fixes the problem.

From past experience possible hd drive going bad, a corrupted font, or a malformed epub.

Just run calibre in a terminal as

calibre-debug -g

if for some reason you cant restart in debug mode.

Thank you! That worked... so now I can get on to figuring out my ORIGINAL problem! (And, by the way, thank you for Calibre!)

baslow · 12-17-2020, 05:07 PM

...and, for the sake of closure, I will report that I was able to generate detailed output using Kovid's suggestion, which allowed me to figure out that the problem I was experiencing with DeDRM was due to, um, stupidity on my part.

I hadn't added any DRM'ed books for quite a while and had neglected to add the serial number for my NEW Kindle. So when I downloaded the books recently, specifying my current device, the plugin didn't have the key it needed. Once I saw the messages output in debug mode it only took a couple of minutes to figure out the problem.

Thanks to everyone!
