pkg upgrade odity

Hi,

pkg wants to remove some package on upgrade. I do not understand why...

# pkg upgrade
Updating FreeBSD repository catalogue...
Fetching meta.conf: 100%    178 B   0.2kB/s    00:01

FreeBSD repository update completed. 467 packages processed.
All repositories are up to date.
Checking for upgrades (1 candidates): 100%
Processing candidates (1 candidates): 100%
The following 4 package(s) will be affected (of 0 checked):

Installed packages to be REMOVED:
         mosh: 1.4.0_2
         netdata: 1.43.2_1
         protobuf: 24.4,1

Installed packages to be UPGRADED:
         rsync: 3.2.7_1 -> 3.3.0

Number of packages to be removed: 3
Number of packages to be upgraded: 1

The operation will free 55 MiB.
405 KiB to be downloaded.

Proceed with this action? [y/N]: n

If I do this instead, it is doing what I expect the former command to 
do:
---snip---
# pkg upgrade mosh netdata protobuf rsync

Any ideas why it wants to remove those packages in the first case?

Bye,
Alexander.
