I seem to have had a failed upgrade, which I seem to have been able to recover from (by using Grub Selector and Recovery Mode and running the Clean and Dpkg tools)
but my Networking (that was working correctly via Wired Ethernet before the upgrade) is knocked out.
In Settings > Networking I can Enable WIred Networking and it seems to go through the motions of trying to connect (though with the Wifi symbol, not the usual Wired Connection symbol) but it then fails and the setting for Wired Connection switches to Disabled.
can anyone help?
