I am using MAAS 3.0 to deploy several HUAWEI RH1288 matal server. I got the following output when running 30-maas-01-bmc-config script

Traceback (most recent call last):

I’m geting the same problem with maas 2.9.2. with HUAWEI XH321.

I’ve found the problem. At least with my HUAWEI machines. When the commision script runs
bmc-config --checkout some odd characters can be found in the section Lan_Conf_Security_Keys

Section Lan_Conf_Security_Keys
## Give string or blank to clear. Max 20 chars
K_R. Ó¶: Î <81>, ^ BØ¡ ^] æZ <9b> <97> ^ E * òN «<9b>
## Give string or blank to clear. Max 20 bytes, prefix with 0x to enter hex
K_G 0x00000000000000000000000000000000000000000000
EndSection

The commissioning script 30-maas-01-bmc-config can’t handle it.
It can be reset using ipmi-config. But after a restart of BMC, the string is back.

1) Create a txt file as
$ cat test.txt
Section Lan_Conf_Security_Keys
   ## Give string or blank to clear. Max 20 chars
   K_R
   ## Give string or blank to clear. Max 20 bytes, prefix with 0x to enter hex
   K_G            0x0000000000000000000000000000000000000000
EndSection

2) use `ipmi-config` and update into BMC
$ sudo ipmi-config --commit --lan-channel-number 1 --filename=test.txt

This was a tip from Ike Panhc in kunpeng920 in Launchpad

There is a bug report on this. https://bugs.launchpad.net/plainbox-provider-checkbox/+bug/1892983

nice work finding this, @glasse

I’m having the same problem.
I try to change the code for line in proc.stdout.decode(errors='ignore').splitlines():
It works for me.

How did you modify the code? I tried to modify the bmc_config.py file, but I didn’t have enough permissions
err

cp /snap/maas/current/lib/python3.8/metadataserver/builtin_scripts/commissioning_scripts/bmc_config.py .
vi bmc_config.py
mount --bind -o nodev,ro bmc_config.py /snap/maas/current/lib/python3.8/metadataserver/builtin_scripts/commissioning_scripts/bmc_config.py
snap restart maas

Thanks！And the file path should be '/snap/maas/current/lib/python3.8/site-packages/metadataserver/builtin_scripts/commissioning_scripts/bmc_config.py’
