The displayed path is wrong on non-dev setups. This as introduced by bug 21846.
There are other occurrences of the pattern in the updatedatabase script: my $upgrade_script = C4::Context->config("intranetdir") . "/installer/data/mysql/labels_upgrade.pl"; my $upgrade_script = C4::Context->config("intranetdir") . "/installer/data/mysql/patroncards_upgrade.pl" There are other places where we don't give a full path, which seems common in other places like the GUI as well: print "If you have records with ean, please run misc/batchRebuildBiblioTables.pl to populate bibliotems.ean\n" if (C4::Context->preference("marcflavour") eq 'UNIMARC'); Would you be ok with changing it to the latter or can we make it work nicely for all installation types?
This is quite old now, so harder to fix/test, maybe more something to keep in mind for the future?
