Hi Alvaro, I think that I actually had a similar experience on Bionic. For the time being, it might just be best to follow the workaround at https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=23653#c11 Although http://swagger.io/v2/schema.json is back up so you shouldn’t experience the program again (while it’s still up).

I think Mason has released a newer version now 3.23+dfsg-1+koha1, which was needed for newer versions of Ubuntu, which used newer versions of libjson-validator-perl than 3.06.

Hi all,

As some people have noticed, http://swagger.io/v2/schema.json is currently unavailable, and this is causing new instances of Plack workers to crash. (New instances can be created by starting Plack or by long-running workers to reach their end of life number of requests.)

The issue is detailed at length in https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=23653.

I think the solution will be for Mason to a libjson-validator-perl package which contains a cached version of that file.

hi Folks i've updated the 'libjson-validator-perl' package to include the cache dir to update the package... $ sudo apt update $ sudo apt install libjson-validator-perl run the following command, and confirm the result... $ apt-cache policy libjson-validator-perl libjson-validator-perl: Installed: 3.06+dfsg-1+koha1 Candidate: 3.06+dfsg-1+koha1 ... cheers, Mason _______________________________________________ Koha-devel mailing list Koha-devel@lists.koha-community.org <mailto:Koha-devel@lists.koha-community.org> https://lists.koha-community.org/cgi-bin/mailman/listinfo/koha-devel website : http://www.koha-community.org/ git : http://git.koha-community.org/ bugs : http://bugs.koha-community.org/ _______________________________________________ Koha mailing list http://koha-community.org Koha@lists.katipo.co.nz <mailto:Koha@lists.katipo.co.nz> Unsubscribe: https://lists.katipo.co.nz/mailman/listinfo/koha
