'verify permissions' error

Hello All,

have been following the advice of the MacForums articles on upgrading from Snow Leopard to Mavericks & have so far , probably in reverse, carried out a back up to Time Machine & have just Verified my hard drive = appears ok & finally Verified Permissions where there was a reoccurring error which it fixed on Request to repair but was unable to address the following, whatever this is, outlined below ; FYI I have never as I am completely unable to use Terminal or tackled the Library folder to the affect to make changes, anyone know what the following means & is upgrading to Mavericks still on the table? I've had no issues to date & I will carry out a second back up now that the Start up disk has been Verified before proceeding & awaiting any advice that's out there.

Thanks everyone.

Kind regards,

Capo Dino

ps I've never used remote management, a little weird, no?
