Error with Plack post upgrade to Koha 25.05.00.000
Hello, Still troubleshooting this but my knowledge of Plack is minimal so I'm hoping someone in the community will have some insights they're willing to share. After a release upgrade to *Ubuntu 22.04.5 LTS* and Koha upgrade to *25.05.00.000*, the following is returned in the Server Information overview: "PSGI: Koha is running in CGI mode. This is a security issue! Run Koha using Plack for CSRF (cross-site request forgery) protection. More information: koha-plack --help" the plack-error log, I have the following: Array found where operator expected at /usr/share/koha/lib/Koha/Patron.pm line 2356, near "zip6 @" (Do you need to predeclare zip6?)

Hello, Let's focus on the error 500. How do you get it? My guess would be that you get "Array found where operator expected" because there is a change between perl version (it seems to work ok for me on 5.36, but with Ubuntu 22.04 you have 5.34). May come from a perl's parser change and the different contextes involved in the expression return @{$a} != @{$b} || notall { $_->[0] eq $_->[1] } zip6 @{$a}, @{$b}; Needs to be confirmed however. Please clarify how you generate this error and I will try on Ubuntu 22.04. Regards, Jonathan Le lun. 2 juin 2025 à 10:51, City & Guilds of London Art School Admin < admin@cglas.ac.uk> a écrit :

Hi Jonathan, Thanks for the ideas. Not sure what you mean by a 500 error there. The web interfaces and their behavior - OPAC and backend - seem fine. Unfortunately at this time I'm unable to say what caused the above, as the log I extracted it from has been error free for the last two days, despite my attempts to trigger the issue both by interacting with Koha and by rebooting the server etc. So far as the System Info page is concerned, Plack still isn't working though, and CGI entries in the access logs back that up. What I can produce reliably is this: /etc/koha$ sudo perl ./plack.psgi -W Can't locate C4/Koha.pm in @INC (you may need to install the C4::Koha module) (@INC contains: /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.34.0 /usr/local/share/perl/5.34.0 /usr/lib/x86_64-linux-gnu/perl5/5.34 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl-base /usr/lib/x86_64-linux-gnu/perl/5.34 /usr/share/perl/5.34 /usr/local/lib/site_perl) at ./plack.psgi line 29. BEGIN failed--compilation aborted at ./plack.psgi line 29. Which makes sense. Koha.pm isn't in any of those paths: sudo find . -type f -iname "Koha.pm" -print ./usr/share/koha/lib/Koha.pm ./usr/share/koha/lib/C4/Koha.pm ./usr/share/koha/lib/Koha/Template/Plugin/Koha.pm The question is, how on earth did that break?! The server IDS was segfaulting when it reach /root/.cpan, which makes me think the OS upgrade broke the CPAN install in some way. If you have any insights based on the above please let me know, otherwise I think my next move will be to clean re-install CPAN.
