Package: debian-parl Version: 1.9.13 Severity: normal gnome-system-tools is unmaintained upstream: it was part of GNOME 2, was last released in 2010 and had its most recent upstream git commit in 2012. Because it deals with user login accounts, it is probably also security-sensitive. This seems like a bad combination.
Metapackages that depend on gnome-system-tools should probably depend on something else with similar functionality instead. Regards, smcv
