Confusing error message when `ipmitool` is not installed

[Jan Marjanovic]

When using mmcterm with ipmitool backend (-i flag) and the IPMI tool is not installed, the following error message is shown:

$ mmcterm -i mch1 0x88
Traceback (most recent call last):
  File "/home/jan/.local/bin/mmcterm", line 8, in <module>
    sys.exit(main())

    int(value, 16) for value in hexstr.split(' ')
ValueError: invalid literal for int() with base 16: '/bin/sh:'

This message is rather confusing, ideally it would mention that the IPMI tool is not installed.

Installing the IPMI tool (sudo apt install ipmitool) fixes this issue.

It is actually a pyipmi issue, I opened a pull request.
