[GUI Plugin] Kobo Utilities

[trishau]

Automatic - default settings. AFAIK - I have never changed anything there. And definitely not changed anything since I removed it and reinstalled!

BTW, I have access to a Macbook, where the plugins work just fine.

Did you install from the Linux repository? If so, you'll want to install fromt he calibre website as repository version are usually broken.

I'm getting the same, but I don't think that's the fault of the Linux packaging, at least on my system:

...and from the Python 3.12 release notes:

configparser no longer has a SafeConfigParser class. Use the shorter ConfigParser name instead.

I've not looked into what it would take to patch/hack the plugin in order to verify that updating that typing fixes things, but even if it's not the specific problem we're running into (and this would be a particularly bad message to expose it if it is), it is at the very least a bug in the plugin.

(Also, don't know about the quality of the packaging on other distros, but I'm on Gentoo where everything is built from source and where "download the binary from the website" is not an acceptable solution.)

Yes you do want to run the calibre binary from the calibre website. My system has Python 3.12.3 installed but runs calibre with no problems.

Well that's horrific, glad I'm building from source to maintain a sane system. Sure is a good thing ConfigParser has had the exact same interface as SafeConfigParser since Python 3.2 (it's probably an alias from that point on, I don't know exactly how they implemented it) while Calibre has packaged at least 3.8 since it first switched to Python 3 almost exactly four years ago (in the leadup to 5.0.0); Kobo Utilities can update the four lines using the deprecated name without affecting anyone who's not using ancient software.

Just try calibre from source and see how you get on. https://calibre-ebook.com A lot of Linux errors are due to the repo version being used.

[theducks]

As to compiling from source.
The source may be fine, and the OS distribution messed up a dependency

[damccull]

Thanks, @WovenTales, for identifying the issue with deprecated stuff in python 3.12. I made a very small patch, following what the python changelog says, and it works great on my calibre. Here's my patched version if anyone's interested. All I did was change SafeConfigParser to ConfigParser in 4 locations. I also bumped the version to 2.17.2 and added a change to the changelog, and added a quick note to the about.txt message for a new source code location. Seems to work great on my machine.

Does anyone know how to get in touch with the cbhaley person who seems to be maintaining this plugin's release? New to the forum and unsure how to do that.

That person is me.

I'm not going to release this until calibre itself uses python 3.12. Doing otherwise is supporting distro builds that change fundamental calibre dependencies, and there be dragons. There are incompatibilities between python 3.11 and 3.12 that affect calibre. Once @kovidgoyal has dealt with those I will look at what is necessary to update the plugin.

Thank you @chaley. I had started a few times to post a pithy reply deakling with these 3rd party repositories and their "philosophical" repackaging of tools like calibre but bit my tongue.
