daemon handling the GNOME/UNITY session settings-requires installation of untrusted

[drorlev]

Hello.

I'm running Ubuntu 14.04 and for quite some time the software-updater suggests to update these packages:

• daemon handling the GNOME session settings
• daemon handling the Unity session settings
• Gnome-settings-daemon schemas

only to return with this message: "requires installation of untrusted packages"

I'll appreciate an explanation and suggestions how to get rid of this.

Thanks!

Well, that was a possible solution but a little more research and found that other possible solution:

sudo apt-get clean

sudo mv /var/lib/apt/lists /var/lib/apt/lists.bak

sudo mkdir -p /var/lib/apt/lists/partial

sudo apt-get clean

sudo apt-get update

Thanks for the replies.

I tried running in the terminal all three commands (update, upgrade, dist-upgrade).

For both upgrade and dist-upgrade I get this message:

WARNING: The following packages cannot be authenticated!
gnome-settings-daemon gnome-settings-daemon-schemas unity-settings-daemon

Any idea why these packages cannot be authenticated? Isn't it worrying that seemingly base packages aren't authenticated?

Would the other (more complicated in my view) way - with the 'clean' command, resolve this?

Thanks!

One explanation would be some PPA for Gnome you might have add. If you haven't then the previous commands should have some effect. Post back if your symptom persists.

Might be helpful to show enabled ppa's.

egrep -v '^#|^ *$' /etc/apt/sources.list /etc/apt/sources.list.d/*.list

egrep -v '^#|^ *$' /etc/apt/sources.list /etc/apt/sources.list.d/*.list

Well, the update-upgrade didn't work and I did have installed some ppa on this machine, so I used CantankRus's suggestion to list my ppa's, found a suspicious ppa, unchecked it from the software-source list and the trouble is over!

Thanks for the help!!
