[webmin-l] Webmin 1.650 (after) upgrade error

[Csere M. <cs...@gm...>]

Hello!

I received the following error during upgrading (post-install script):

sh: -M: invalid option
Usage:	sh [GNU long option] [option] ...
	sh [GNU long option] [option] script-file ...
GNU long options:
	--debug
	--debugger
	--dump-po-strings
	--dump-strings
	--help
	--init-file
	--login
	--noediting
	--noprofile
	--norc
	--posix
	--protected
	--rcfile
	--restricted
	--verbose
	--version
Shell options:
	-irsD or -c command or -O shopt_option		(invocation only)
	-abefhkmnptuvxBCHP or -o option

After that i am receiving the same error when my cron runs /etc/webmin/status/monitor.pl

What could be causing this behavior?

Thank you,
cserem
