[Koha-devel] Koha packaging problems (Deb10/Buster)

[dcook at prosentient.com.au]

Wait a minute... why do we need to pin libmojolicious-perl? 

Thanks to Ere's work on https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=22522, Koha should be able to work with Mojolicious 8 now (and Mojolicious::Plugin::OpenAPI 2.21 and JSON::Validator 3.18). Admittedly it's only in master right now, but I'm using his patches on 18.11 and 19.11 already with Mojolicious 8, and they're working well so far. So hopefully people start pushing that code to stable branches ASAP.

hmm, i had forgotten another...
its possible to tell apt to prefer koha's older mojo v7 package, rather than the newer debian/buster mojo v8 package

running the following command before 'apt install koha-common' makes it possible to run the various koha releases on debian 10

$ sudo cat << EOF > /etc/apt/preferences.d/koha-1001
Package: libjson-validator-perl
Pin-Priority: 1001
Pin: release o=Koha

Package: libmojolicious-perl
Pin-Priority: 1001
Pin: release o=Koha
EOF


for me, this option is probably the easiest workaround for koha on debian 10

if nobody objects? - i am happy to update the koha wiki with this workaround

cheers, Mason
