Hello,
my router CCR1016-12G have version: 6.37 (stable). I am install ntp-6.34.6-tile.npk, but router has not ntp server.

[router] > system ntp
client export

Please, help me.

Pakage system-6.37.1-tile.npk install too, but situation not change.

I guess that package version must be equal to installed RouterOS version.

If you have ROS 6.37 you must have package 6.37
If you have ROS 6.37.1 you must have package 6.37.1
... and so on , so: upgrade ROS to 6.37.1 and than install package.

I'm upgrade mikrotik to 6.37.1 (Current)

> system resource print
uptime: 1d6h57m55s
version: 6.37 (stable)

But ntp server doesnt in configuration. The problem temporarily solved by redirect port 123 to working ntp server.

Like th0massin0 mentioned before, take good notice of the applicable version.
If you would like to add a package, upload the file from the corresponding version as your router is running.
You said you upgraded, but the printout is stilll showing 6.37 (not .1)

Use same package version for the system package and the optional ntp package. Be sure that the package is successfully installed.
Execute the command >system package print
to be sure the ntp package is listed as installed package therein.
