Artifacts are the output of job runs on GitHub. The op is trying to download the beta version from GitHub; there is no release version for the beta build.

Does this mean that there is no functional version downloadable right now? Last time I tried the official version, I had a bunch of errors...

I'm on Linux and I'll have to look what the version is when I come home. The latest on Flathub!

It is Calibre 8.6.

This link will download the latest version with tested commits. It is what I use on my Linux Mint system with no problems.

Try the real calibre 8.6 from the calibre site and see if that helps.

It is the real calibre, just runs in a container.

Maybe you should try Linux and then run Flathub calibre.

Jon,
Calibre flatpak is the real Calibre. You can verify this for yourself by comparing file checksums.

Hi Bernie, would you please share how you installed it? When I install via the Master.zip then I get a bunch of errors when trying to load the calibre-plugin. This happened before as well, until I found that using this artifact https://github.com/Leseratte10/acsm-...ns/14431491679 was working. But now it seems to be expired, and I get the same errors I got back then.

If it is the real calibre, try running it normally without flatpak.

I run Fedora Silverblue which works almost exclusively via Flatpacks... I could layer it, but try to avoid that. The plugin worked well a few weeks ago on a Flatpack version but I had to to a clean reinstall of my OS and now can't access the same files anymore (I had saved all the links with the right files).

Calibre in a Flatpak container is 100% exactly the same code running the same as Calibre from a tarball. The ACSM plugin loads and runs exactly the same -- or fails exactly the same. Why would you think that it is somehow different?

But I'll humor you.

flatpak --command="bash" run com.calibre_ebook.calibre
cp -rpv /app ~/Desktop
exit # we leave the Flatpak container environment to the "normal" environment.
cd Desktop
sudo cp -rpv app /app
cd /app/lib/calibre/resources/fonts/liberation
sudo rm *.ttf
sudo cp /usr/share/fonts/truetype/Liberation* . # your path may vary
/app/bin/calibre --version
calibre (calibre 8.6)
/app/bin/calibre # and my libraries load up "normally".

Without Flatpak, if the ACSM plugin working?

[gbm]

Extract the acsm-calibre-plugin-master.zip file that you downloaded. Go to the folder acsm-calibre-plugin-master. Inside that folder will be the following files/folders:

Folders:

calibre-plugin
migration_plugin
tests
.github*

Files:
bundle_calibre_plugin.sh
bundle_migration_plugin.sh
LICENSE
package_modules.sh
README.md
.gitignore*

*hidden files

Now double click on the bundle_calibre_plugin.sh file--if it asks if you want display or run click run--this will build the file calibre-plugin.zip.

Go to plugins in calibre and click load plugin from file, then navigate to the calibre-plugin.zip click on it then click ok.

That will load the plugin, now you will have config it.

I highly recommend that you get a usb stick and copy your calibre config folder to it and keep it up dated that way if you ever have to do a clean install in the future you will have all of your plugin saved.
