I've been using Zorin 17.2 for a few months now on my Inspiron 15 without any major issues, been able to install/remove software pretty easily, etc. However, whenever I turn the laptop on now I get a message about major updates not installing.
I've tried to update my software using Terminal without luck, and when I open the Software app there's an Integrated Firmware update sitting there waiting to install. I'm not sure what this is, and although I've selected both the 'Update' and 'Update and Restart' buttons, the installation just hangs without any progress.
Thanks for helping out. I'm not sure what I've done, but the error appears to have resolved itself without me doing anything. I've reinstalled gnome-software just in case, but everything seems fine for the moment.
