Simply removing the faulty package worked for me.

$ dpkg -S appstreamcli
appstream: /usr/bin/appstreamcli
appstream: /usr/share/man/man1/appstreamcli.1.gz
$ sudo apt remove appstream

Should I really be issuing the sudo rm command while drunk?

Maybe bad idea.

EDIT: Even worse, you didn't say to use sudo rm. Yea, I'm done with terminal for now.

What does this app do, exactly?

I've disabled the auto update for apt on my mythtv backend server to prevent this from taking up all the CPU. But I am not sure I should uninstall this package since I'm not sure what effect it will have on mythtv working?

Thanks!

You can read about it here: https://www.freedesktop.org/wiki/Dis...ons/AppStream/ and check man appstreamcli if you have appstream installed. I don't. It isn't part of Lubuntu

Seems it's something since 15.10 that

provides the foundation to build software-center applications, by providing metadata necessary for an application-centric view on package repositories. AppStream additionally provides specifications for things like an unified software metadata database, screenshot services and various other things needed to create user-friendly application-centers for (Linux) distributions. ...

The specification now also contains a description of DEP-11, which is a YAML-based version of the distro XML specification used by Debian and its derivatives.

I was wondering about this DEP-11 business.

apt show appstream indicates that this thing is part of the following DEs:

Code:

ubuntu-desktop, ubuntu-usb, kubuntu-desktop, kubuntu-full, edubuntu-desktop, edubuntu-usb, xubuntu-desktop, 
mythbuntu-frontend, mythbuntu-desktop, mythbuntu-backend-slave, mythbuntu-backend-master, 
ubuntustudio-desktop, ubuntu-gnome-desktop, ubuntukylin-desktop

Thanks, I guess I better not remove it! I am using xubuntu-desktop for the mythtv-backend since the mythtv setup requires a GUI as far as I know to set up tuners, etc.
