Description

Is it regression?

no

Expected behavior

$PATH is identical between x86 and arm64 or at least $PATH on arm64 should contain /home/runner/.local/bin just like on x86 as the user the job is running as is runner and not runneradmin.

Actual behavior

$PATH is different and contains /home/runneradmin/.local/bin instead of /home/runner/.local/bin

Repro steps

• echo $PATH
