Home Assistant CLI - Core check

I have been working on updating the core to 2024.2.1 for a while now.
I cannot do this by default via HA. Now I have connected the Raspberry Pi4 directly to a monitor and attached a keyboard to it.
I can see the CLI. When I give the core check command, it goes ‘processing…’ after a while I get an error message “INFO: task kworker/0:2:37 blocked for more than 120 seconds.” then: “Tained: g. C. 6.1.63-haos-raspi #1” and then “Echo 0> proc/kernel/hung_timeout_secs” disables this message.

Updating via the CLI is also not possible. Anyone have an idea how to solve this?
