Update errors for blueman

[csias40]

Getting these update errors for the last 2 weeks and updates fail.I removed blueman and dropbox, and then it works, but how do I get bluetooth to work?
I was trying to make bluetooth work, but it doesn't like the repositories.Tried the instructions here, but they are from 2014.  Any suggestions?
