Hi
It seems I ticked all the boxes but my EPUBcheck plugin still fails at every book with the same error message (see image below).
Code:
[roger@roger-lenovo ~]$ archlinux-java status
Available Java environments:
java-11-openjdk
java-21-openjdk
java-8-jre/jre (default)
[roger@roger-lenovo ~]$ python -V
Python 3.11.6
[roger@roger-lenovo ~]$ java -version
java version "1.8.0_391"
Java(TM) SE Runtime Environment (build 1.8.0_391-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.391-b13, mixed mode)
Sigil selects automatically /usr/bin/python3 on my Preferences.
In September I had downloaded epubcheck 5.0.1. This time, it seems that I fail to download the update (5.1.0.) probably because of my current location, but nevertheless, the plugin should launch the old version.
