The current version is 3.2.7, especially 2.6.8 is quite ancient.

I had noticed that adding --itemize-changes to the command line did
not result in any additional output.  Dunno why, nor whether the two
issues might be related.

You have --itemize-changes but either it didn't or you filtered it out.

The question is:  why does rsync attempt (and fail) to change the
permissions of two destination directories, and not the other two,
when the permissions of all four destination directories already
match the corresponding source directories?  (The change attempt
fails because of the destinations' uchg,uunlnk flags, but as far
as I can see the change should never have been attempted in the
first place.)
