Package: gnome-core Version: 1:44+1 Severity: normal gnome-core is generally useful for maintaining a Gnome desktop environment. gnome-software is not.
Some people find gnome-software useful, but it is certainly not core for a Gnome environment when apt is used for package installation. On the contrary, gnome-software introduces other problems, including an unwelcome packagekitd dependency. The two together are currently spamming syslog (Bug#1064364). All the problems associated with gnome-software could be alleviated simply by making gnome-core Recommend: gnome-software, instead of Depends:.
