Got TypeError: unsupported format string passed to bytes.__format__ when listing sensors

[rpelissi]

Hi! So, I am trying to use the python module to get the health of my system using the sensors. So I have outragously took part of the code in ipmitool to have this sensors and their values. But on a supermicro server, I an error (sometimes it's a timeout, sometimes, an error). When I run the ipmitool, I got this:

$ ipmitool.py -I rmcp -H 10.65.xxx.xx -U ADMIN -P XXXXXX sdr  list

Any idea on how I can debug this? I am not too familiar with ipmi but if I can give you more infos, just let me know! Thanks again for this code!
