Error in agent bakery plugin file apt: leading zeros in decimal integer literals are not permitted

[nisamudeen97]

CMK version : Checkmk 2.0.0b7
OS version : Debian 9

Error message : Error in agent bakery plugin file apt: leading zeros in decimal integer literals are not permitted; use an 0o prefix for octal integers (, line 10)

Explanation. We have recently upgraded from checkmk 1.6 to 2 version. After the upgrade we are unable to apply the changes. The attach screen shot error is displayed

OMD[kaikaito]:/opt/omd$ cmk -R
Generating configuration for core (type cmc)…Creating helper config…OK

Is it possible that this is an old modified or own created bakery plugin?
In version 2.0 there is no bakery script with only the name “apt”.
Can you please run the cmk -R also with “cmk --debug -vvR”?

It is an own created Bakery plugin, we have upgraded from 1.6 to 2.0 . Below is the result of
“cmk --debug -vvR” command

@nisamudeen97

It is an own created Bakery plugin, we have upgraded from 1.6 to 2.0

Then it is possible that it will only work if you made some changes to this bakery script.
Remove the 0 before 755 and it should work again.
