Ubuntu 16.04, update from 126.96.36.199 to 1.4.2:
meteor update --patch
You are attempting to run Meteor as the “root” user. If you are developing,
this is almost certainly not what you want to do and will likely result in
incorrect file permissions. However, if you are running this in a build process
(CI, etc.) or you are absolutely sure you know what you are doing, add the
--unsafe-perm flag to this command to proceed.
sudo meteor from user,
and any experiments with flags have not given result,
are you confirm it?
