I can not start with umbrel.
My system Raspberry Pi 4 Model B with 8GB RAM
Can anyone help me?
Seems hardware problems. Do you use a SSD? If so, test the disk system, by looking the copy speed of a large file (> 1GB) from the disk to itself. It must be greater than 100MB/s for a health SSD storage system. If lesser speed, you have a cable or adaptor or ssd issue.
You were right.
I replaced the hard drive cable and the problem was fixed.
