Support Request

In case you need support or you found a bug it's all about informations that you need to deliver.

Usual request

To provide a log, please go to System -> Log in the WebUI and copy the log. Then create a paste at with the copied log. Once you have the Pastebin link, please open a issue on Github, fill out the template and provide the Pastebin link.

Segmentation faults

Debugging segmentation faults requires a bunch of work, if we don't own your hardware (idr one of these plenty ARM systems) or can't reconstruct the segmentation fault we need a backtrace log from you. In order to create one, follow these steps.

  • You need a "Debug" version of Hyperion, download and install it over your existing installation.
  • Install "GDB", gbd is a tool which is often used for debugging. Get it from the software repository of your distribution (Debian e.g. sudo apt-get install gdb

Steps of execution

  • Open a terminal
  • Make sure Hyperion is NOT running, this can be done by typing sudo service hyperiond stop into the terminal and press enter
  • Type in gdb and press enter. You will now see the gdb welcome information and a "(gdb)" in front of your cursor
  • Tell gdb where "hyperiond" is located, usually at /usr/share/hyperion/bin/hyperiond. Prepend "file" to the path. So type into terminal something like that and press enter: file /usr/share/hyperion/bin/hyperiond
  • gdb should tell you now that the binary has been loaded with it's symbols etc
  • Now type in run and press enter, this will start Hyperion. Now you can use Hyperion as usual, repeat the steps you did to create a segmentation fault.
  • A segmentation fault happened, when Hyperion stops responding and you see something like this as last message at the terminal: Thread 1 "hyperiond" received signal SIGSEGV, Segmentation fault.
  • Now type in backtrace and press enter, add the backtrace to your support request thread at our forum. Hyperion Project Forum
  • To quit gdb press enter and type in quit, you can start Hyperion again with sudo service hyperiond start. It's not recommended to use "Debug" Hyperion builds in production, just install the "Release" version again.
