This bug relates to these installation documents: - https://wiki.koha-community.org/wiki/Preparing_your_system - https://wiki.koha-community.org/wiki/Koha_on_Debian Since installation on Debian 10 is currently discouraged, I attempted a koha install on a fresh instance of Debian 9, 64-bit (i686) architecture. The problem occurs at the "Install Koha" step (https://wiki.koha-community.org/wiki/Koha_on_Debian#Install_Koha). The command "apt-get install koha-common" fails with the following error message: Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: koha-common : Depends: libnet-oauth2-authorizationserver-perl but it is not going to be installed E: Unable to correct problems, you have held broken packages. This is a known problem, mentioned in bug 23128 (https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=23128). The workaround that is suggested there is to enable Debian 9 backports, as follows: 1) Create /etc/apt/sources.list.d/stretch-backports.list with this line: deb http://deb.debian.org/debian stretch-backports main 2) Run apt-get update Running "apt-get install koha-common" will then work. This workaround should be incorporated into the "Koha on Debian" document. Without it, installation fails.
I signed up for wiki access and changed the "Koha on Debian" document so it now has instructions for including stretch backports. Marking this RESOLVED as it fixes a documentation bug; however the underlying problem in bug 23128 is still out there.
