Bug#863102: epubcheck: exec format error

[Sébastien Hinderer]

Could it be that, seven years later, I am having the same problem?

$ epubcheck -h > /tmp/log 2>&1
Gives an exit code 2 and here is the output of the log:
/usr/bin/epubcheck: ligne 1: $'PK\003\004' : commande introuvable
/usr/bin/epubcheck: ligne 8: erreur de syntaxe près du symbole inattendu « ( »

$ file /usr/bin/epubcheck
/usr/bin/epubcheck: symbolic link to ../share/java/epubcheck.jar
$ file /usr/share/java/epubcheck.jar
/usr/share/java/epubcheck.jar: Zip archive data, at least v1.0 to
extract, compression method=store

It may be worth noting that this was working alright until recently.
Then I installed calibre, which I think did upgrade a number of
packages. Could it be that the kernel new how to execute Java files and
dooes no longer know  how to do that?
