https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=32065 --- Comment #2 from Victor Grousset/tuxayo <victor@tuxayo.net> --- It's only happening the Ubuntu 18.04 on the CI Which I also happen to use, let's try. Confirmed! Maybe the YAML is valid and the particular version of the OS of the failing build has a bug. Checking against external tools and YAML specs might be needed to be sure what's wrong. root@kohadevbox:koha((2200b4aa3d...))$ prove xt/yaml_valid.t xt/yaml_valid.t .. 1/18 # Failed test '/kohadevbox/koha/xt/../koha-tmpl/intranet-tmpl/prog/en/modules/admin/preferences/i18n_l10n.pref is YAML' # at xt/yaml_valid.t line 41. # Failed test '/kohadevbox/koha/xt/../koha-tmpl/intranet-tmpl/prog/en/modules/admin/preferences/serials.pref is YAML' # at xt/yaml_valid.t line 41. # Failed test '/kohadevbox/koha/xt/../koha-tmpl/intranet-tmpl/prog/en/modules/admin/preferences/local_use.pref is YAML' # at xt/yaml_valid.t line 41. # Looks like you failed 3 tests of 18. xt/yaml_valid.t ..
