  • [BUG] Dump1090-Mu: AJAX Error Problem Fetching Data

    Reports this week that Dump1090 local map on FR24feed setups is now reporting errors about data not found

    - Possibly specific to FR24feed script install when 'DVBT' selected - Separate or Dump1090-FA install does not appear effected

    At this point believed to be related to the newly modified remote SDR blacklist rules being auto updated by a package related to Dump1090/SDR tools and blocking access to the USB dongle instead of fixing it.

    Code:
    sudo wget -O /etc/udev/rules.d/rtl-sdr.rules "https://raw.githubusercontent.com/osmocom/rtl-sdr/f2a9a81/rtl-sdr.rules"    
    
    sudo reboot

    Tested. YES above revised bug-fix works
    (uses old rtl-sdr.rules file)

      EASY BUG-FIX
      No need to download the file "rtl-sdr.rules".
      Simply add user "dump1090" to group "plugdev" (the group recently added to "rtl-sdr.rules" in commit b281473), and that does the job
      (This is based on fact that the last modifications to "rtl-sdr.rules" includes, among other things, addition of GROUP="plugdev")

      Code:
      ## Check
      $ groups dump1090
      dump1090 : nogroup
      
      ## Add user dump1090 to group plugdev
      $ sudo usermod -a -G plugdev dump1090
      
      ## Check again, dump1090 is now added to group plugdev
      $ groups dump1090
      dump1090 : nogroup plugdev
      
      ## Restart dump1090-mutability
      $ sudo systemctl restart dump1090-mutability
      
      ## Check gmap.html, it is live now :)
