[SOLVED] System won't update

[Always_In_The_Moode]

Very odd.

Hi Tim

Yes it is!

I remember ssh'ing into the box and poking around, I saw a bunch of connection errors when I ran 'sudo apt update' to see what happens. There was something clearly wrong with connectivity. 

I then realised just now that I was encountering some strange issues with Windows Update and the Microsoft Store not working correctly on another PC. It turns out that after about a week or two, something in my Vodafone UK Broadband router goes wrong causing these strange issues to suddenly appear requiring a reboot to clear. The bizarre thing is that during all this everything else still works fine, like general web browsing. 

So having rebooted the router earlier, I tried again. And this time, the upgrade worked fine.

I thought I'd put it out there in case it helps anyone else. Sometimes the root cause isn't always obvious!
