I experienced some issues while upgrading my Vero 4K via ssh with apt-get update and apt-get dist-upgrade.
Firstly, when the new samba package got installed, it came up with a curses-y dialog telling me my config was borked because it had include lines in it, and asked me to choose whether to overwrite my config file or not. Although I chose to, it looks like the only change was commenting out the 'usershare template share' line and adding an associated comment, so all's well that ends well.
Later, as the connman update was being applied, I lost all network connectivity and had to power cycle. It later transpired that it had opted to change it's IP address for reasons beyond my ken (DHCP, wired).
Following the power cycle, kodi crashed after ~5s, and I got a sad face and a reboot. Not got debug logging enabled atm, so I'm afraid I cannot share logs of this.
Seems to be working now though. And it looks like the Menu settings are being saved too!
