Trouble Updating

I am not 100% sure from the logs but suggest the following steps:

  1. Apply hotfix as shown in the v19 FAQ
    Kodi v19 troubleshooting FAQ

  2. Then try another manual update

If problem remains you would need to connect via SSH and run
sudo apt-get update
sudo apt-get dist-upgrade
And share the error output.

Not related to your issue but still a correction of your setup

We recommend people with 4K TV’s set their user interface (UI) to 1080p. Kodi’s UI is not optimized for 4K yet and this can put unnecessary demands on your device and can lead to a suboptimal picture quality, as well as potentially cause other issues.

The settings we recommend are as follows…

Settings>System>Display>Resolution> 1920x1080p
Settings>System>Display>Whitelist> (empty) *
Settings>Player>Videos>Adjust display refresh rate> On start/stop

Some televisions may also need, or benefit from, the following being set…

System>Display>Force 4:2:2 colour subsampling> (enable)

With the above settings your UI will be output in Full HD and your 4K content will be output in 4K. *Information regarding the whitelist can be found here. If you have any doubt, feel free to upload some logs so we can verify that your settings are indeed correct.
