This bug affects me also. I'm assuming it is something related to /var/cache being mounted as a tmpfs
I haven't tried the [Unity notification "Update Manager" icon -> Install updates] trick. Do you right click on the icon to get this option? When I run... ~$ update-manager from a terminal it doesn't work even if I right click on the icon. How do I get the unity notification? When running from the command line I get these warnings... ~$ update-manager WARNING:root:directory '/var/cache/apt/archives' does not exists ERROR:root:Not enough free space: ['/var/cache'] WARNING:root:directory '/var/cache/apt/archives' does not exists ERROR:root:Not enough free space: ['/var/cache'] gpg: /tmp/tmpGDw2Px/trustdb.gpg: trustdb created I check manually for /var/cache/apt/archives... ~$ ls /var/cache/apt/ pkgcache.bin srcpkgcache.bin I create /var/cache/apt/archives... ~$ sudo mkdir /var/cache/apt/archives [sudo] password for jesse: I run update-manager again... ~$ update-manager SUCCESS!!! I try installing updates... The updates work but I get the following list of error messages in the terminal... <quote> (update-manager:20288): Gtk-WARNING **: /build/buildd/gtk+3.0-3.4.2/./gtk/gtkliststore.c:851: Unable to convert from glong to gint (update-manager:20288): Gtk-WARNING **: /build/buildd/gtk+3.0-3.4.2/./gtk/gtkliststore.c:851: Unable to convert from glong to gint (update-manager:20288): Gtk-WARNING **: /build/buildd/gtk+3.0-3.4.2/./gtk/gtkliststore.c:851: Unable to convert from glong to gint (update-manager:20288): Gtk-WARNING **: /build/buildd/gtk+3.0-3.4.2/./gtk/gtkliststore.c:851: Unable to convert from glong to gint (update-manager:20288): Gtk-WARNING **: /build/buildd/gtk+3.0-3.4.2/./gtk/gtkliststore.c:851: Unable to convert from glong to gint (update-manager:20288): Gtk-WARNING **: /build/buildd/gtk+3.0-3.4.2/./gtk/gtkliststore.c:851: Unable to convert from glong to gint (update-manager:20288): Gtk-WARNING **: /build/buildd/gtk+3.0-3.4.2/./gtk/gtkliststore.c:851: Unable to convert from glong to gint (update-manager:20288): Gtk-WARNING **: /build/buildd/gtk+3.0-3.4.2/./gtk/gtkliststore.c:851: Unable to convert from glong to gint (update-manager:20288): Gtk-WARNING **: /build/buildd/gtk+3.0-3.4.2/./gtk/gtkliststore.c:851: Unable to convert from glong to gint (update-manager:20288): Gtk-WARNING **: /build/buildd/gtk+3.0-3.4.2/./gtk/gtkliststore.c:851: Unable to convert from glong to gint (update-manager:20288): Gtk-WARNING **: /build/buildd/gtk+3.0-3.4.2/./gtk/gtkliststore.c:851: Unable to convert from glong to gint (update-manager:20288): Gtk-WARNING **: /build/buildd/gtk+3.0-3.4.2/./gtk/gtkliststore.c:851: Unable to convert from glong to gint (update-manager:20288): Gtk-WARNING **: /build/buildd/gtk+3.0-3.4.2/./gtk/gtkliststore.c:851: Unable to convert from glong to gint (update-manager:20288): Gtk-WARNING **: /build/buildd/gtk+3.0-3.4.2/./gtk/gtkliststore.c:851: Unable to convert from glong to gint (update-manager:20288): Gtk-WARNING **: /build/buildd/gtk+3.0-3.4.2/./gtk/gtkliststore.c:851: Unable to convert from glong to gint (update-manager:20288): Gtk-WARNING **: /build/buildd/gtk+3.0-3.4.2/./gtk/gtkliststore.c:851: Unable to convert from glong to gint (update-manager:20288): Gtk-WARNING **: /build/buildd/gtk+3.0-3.4.2/./gtk/gtkliststore.c:851: Unable to convert from glong to gint (update-manager:20288): Gtk-WARNING **: /build/buildd/gtk+3.0-3.4.2/./gtk/gtkliststore.c:851: Unable to convert from glong to gint (update-manager:20288): Gtk-WARNING **: /build/buildd/gtk+3.0-3.4.2/./gtk/gtkliststore.c:851: Unable to convert from glong to gint debconf: DbDriver "passwords" warning: could not open /var/cache/debconf/passwords.dat: Permission denied debconf: DbDriver "passwords" warning: could not open /var/cache/debconf/passwords.dat: Permission denied debconf: DbDriver "passwords" warning: could not open /var/cache/debconf/passwords.dat: Permission denied debconf: DbDriver "passwords" warning: could not open /var/cache/debconf/passwords.dat: Permission denied debconf: DbDriver "passwords" warning: could not open /var/cache/debconf/passwords.dat: Permission denied debconf: DbDriver "passwords" warning: could not open /var/cache/debconf/passwords.dat: Permission denied </quote> I'm wondering if these are just messages that would appear anyway and are not related to this bug? Any one know? I'm assuming that they are.
