[OS X TeX] [OS X TEX] TeX Live Utility can't update itself

Running TLU version 1.30 it requires to be updated.  I’ve receive a checksum error in this process:

2017-08-04 13:56:34 +0000 Warning tlu_ipctask[58625]	Error in MD5 checksums: 3bea46117831ffa4c219f89b6b8809f2 is different from b7ab95b13a95167223f4096fd9a9bd4f

2017-08-04 13:56:35 +0000 Notice -[TLMAuthorizedOperation _runUntilChildExit][58493]	kqueue noted that tlu_ipctask (pid = 58625) exited with status 2

so the updating stopped.  Am I doing something wrong?
