Package manager, load_average undefined errors

[LexArma]

Installing packages on SMF 2.1.1 causes undefined index errors for me. I got these two on the same second while installing a package, the installation is succesful though.

?action=admin;area=packages;sa=install2;package=1613849140.zip;pid=0 /httpdocs/Sources/Load.php (Line 341)
"8: Undefined index: load_average"

?action=admin;area=packages;sa=install2;package=1613849140.zip;pid=0 /httpdocs/Sources/Load.php (Line 337) "8: Undefined index: load_average"

I would suspect the cause and solution to be the same or similar as here https://github.com/SimpleMachines/SMF2.1/pull/4804
