Package sysvinit is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
systemd-sysv upstart sysvinit-utils sysvinit-core file-rc
E: Package ‘sysvinit’ has no installation candidate
./install: Zeile 676: php: Kommando nicht gefunden.
