[Solved] How can I set the Software Center to install software for non-root users? For Kubuntu Users:

Kubuntu uses QAptWorker as backend (observed for Natty and Oneiric). To allow for non-root installations, create /etc/polkit-1/localauthority/50-local.d/10-allow-non-root-install-packages.pkla containing:

[Update Software Sources]
Action=org.kubuntu.qaptworker.updateCache
ResultAny=no
ResultInactive=no
ResultActive=yes

[Install Software]
Action=org.kubuntu.qaptworker.commitChanges
ResultAny=no
ResultInactive=no
ResultActive=auth_self

I want to allow some non-admin users to install software while not granting sudo access directly. That was accomplished by inserting the next lines in both configuration groups:

Identity=unix-user:some-non-admin-user

If there is a group that must be granted permission, use unix-group instead of unix-user.

[Update Software Sources]
Action=org.kubuntu.qaptworker.updateCache
ResultAny=no
ResultInactive=no
ResultActive=yes

[Install Software]
Action=org.kubuntu.qaptworker.commitChanges
ResultAny=no
ResultInactive=no
ResultActive=auth_self

For Ubuntu users:

You can modify the PolicyKit permissions to allow the users to access the aptdaemon backend that Software Centre uses.

dpkg --listfiles aptdaemon shows that /usr/share/polkit-1/actions/org.debian.apt.policy is the file specifying the actions possible on the aptdaemon backend.

Looking in that file, the < action id=""> tags specify the possible actions. You’d probably want org.debian.apt.install-packages to allow users to install new packages from the archive, and org.debian.apt.update-cache to allow users to update the package lists.

See man pklocalauthority which documents how to set local permissions on PolicyKit actions. Putting the following into /etc/polkit-1/localauthority/50-local.d/10-allow-users-to-install.pkla will allow any user logged in to the local machine to install packages after typing their own password (even when they’re not in the admin group) and to update the package cache without typing any password.

[Untrusted Install]
Action=org.debian.apt.install-or-remove-packages
ResultyAny=no
ResultInactive=no
ResultActive=auth_self

[Untrusted Update]
Action=org.debian.apt.update-cache
ResultAny=no
ResultInactive=no
ResultActive=yes

This I found for Ubuntu 18.04:

To make this working in my Ubuntu 18.04, I had to change the /etc/polkit-1/localauthority/50-local.d/10-allow-users-to-install.pkla file to:

[Untrusted Install]
#Action=org.debian.apt.install-or-remove-packages
Action=org.freedesktop.packagekit.package-*
ResultyAny=no
ResultInactive=no
ResultActive=auth_self
Identity=*

[Untrusted Update]
Action=org.debian.apt.update-cache
ResultAny=no
ResultInactive=no
ResultActive=yes
Identity=*

[Admin Install]
#Action=org.debian.apt.install-or-remove-packages
Action=org.freedesktop.packagekit.package-*
ResultyAny=no
ResultInactive=no
ResultActive=yes
Identity=unix-group:adm
