[wpkg-users] Install/Upgrade a package only if this program is installed

[Rainer Meier]

Hi,

Currently there is no such feature because it would mean to follow a
completely different approach. You would need checks to check if a
program is installed and additional checks which verify the installed
version. These checks are not necessarily identical.

In a future version of WPKG I plan a feature which allows the user to
install packages using WPKG and manually added packages are treated the
same way as if they were added by the profile allowing automatic
upgrading even if the package is not part of the profile. Of course this
would require the user to have rights to install the package (but not
necessarily admin rights if the package can be installed properly
without admin rights).

However this still implies that the package has been installed using
WPKG (and not manually).

br,
Rainer
