The configured LOGFILE can not be modified.

@fbartels: Strange, but the errormessage while installing via apt-get was the same as mentioned in this thread. Did the chown. It is working now.

@fbartels That is a nice, but wrong example.

set_perms www-data www-data 700 /var/lib/z-push
set_perms www-data www-data 700 /var/log/z-push

should be

set_perms www-data adm 750 /var/lib/z-push
set_perms www-data adm 750 /var/log/z-push

Confirm debian policy. ;-)

install -d /var/lib/z-push -o www-data -g adm -m 750
install -d /var/log/z-push -o www-data -g adm -m 750

where user/group should be the variable to set to match the correct user/group per distro.

@thctlo your version may include more Debianisms (the adm group), but in the end achieves the same. The www-data user needs read/write permissions.

So I would not say the current way is “wrong”.

[thctlo]

yes, i do, because the "administrative group " adm, should have read access.
which is/was in Red Hat : wheel
but i can not confirm it that is still.
