[Bug] Assertion failed while syncing from scratch and stuck at height 1802252/4446102

[mehditlili]

What happened?

On Ubuntu 22.04, installed chia via apt install and started the node in order to sync from scratch.

chia start node

Syncing has reached height of 1802252/4446102 then got stuck there. I am syncing on an i5 13400 so CPU here is definitely not the problem.

When I checked the logs with tail -F ~/.chia/mainnet/log/debug.log

I get

2023-10-30T10:57:39.063 full_node chia.full_node.full_node: ERROR    sync from fork point failed: AssertionError:

Seems I have Disk IO errors on my system. So it is probably that.
