Hi Mark,

it is 8.4-RELEASE-p19.

I found out something new to me in handbook:

When upgrading an existing system that originally used the older package 
system, the database must be converted to the new format, so that the 
new tools are aware of the already installed packages. Once pkg has been 
installed, the package database must be converted from the traditional 
format to the new format by running this command:

|#|  *|pkg2ng|*


      Note:

This step is not required for new installations that do not yet have any 
third-party software installed.

Does it connect with my error somehow ?

Durring last freebsd-update there were not any info about new pkg db 
generation.

I do not remember that I had to execute this command.

Best regards,

Daniel
