# The behaviour will be:
# A. If "sudo -l" wants a password (some installations!):
# If a matching rule with !authenticate is found, no passwd will be asked and retno is 0
# If there is a rule matching with no !authenticate, then a password would be asked. This is prevented, so there will only be the
# error "a password is needed" an retno is 1
# If there is no sudo rule at all, it will only set retno to 1
#-> Anyway, returning > 0 means the user is not allowed to run sw installation, which is fine. Print Message and skip installation.
#
# B. If "sudo -l" doesn't not want a password, then
# RETNO = 0 , but the Output of "sudo -l -l" must als be checked, if there is an Option !authenticate in the returnung string, otherwise a failed installation cannot be
# divided from a missing sudo-rule
