They don't just behave different, they are different. Manager relys on the complete archive cache, installer relys on app-install-data. Simply put: manager can install everything, installer only applications with GUI (more precise, such which ship a desktop file in usr/share/applications). That is the reason you can find hddtemp with manager, but not with installer.
The plasmoid issue is basically due to the same reason (their desktop files are not shipped in the path stated above). Fixing this would have to be done in app-install-data-ubuntu, so please report a bug to include plasmoids in the database of app-install. Thank you for this report. ** Changed in: adept (Ubuntu) Status: New => Invalid -- search in adept installer inconsistent with manager https://bugs.launchpad.net/bugs/285694 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
