Hi,

When upgrading to 10.13.66-1 from 6.12.65-32 logged in as root I get the following messages:

Will this cause any kind of problems when continuing the upgrading process or could I just ignore them?

If I continue to the next upgrade script upgrade-10.13.66-2.sh, there are no errors in Stage 3 to 5.

Thanks!
