Stuck in Single User Mode

Post by Zyhru »

I turned on my ODROID-XU4 yesterday night and I can't get passed "Single User mode".

I get the output:

proc: Bad value for 'hidepid'
Give root password for maintenance
(or press Control-D to continue):

When I press Control-D then I get another output:
sulogin: input overrun at /dev/tty1

Whenever I try to reboot, it always goes to this console.... how can I approach this problem?

Which Ubuntu version did you flash?
Is this one?

You should probably enter root password (odroid if not changed) and investigate logs (dmesg, /var/log/messages, /var/log/syslog). If it's complaining it can't mount the rootfs, you should run fsck on it.

I ordered an eMMC that had Pre-installed Ubuntu.

I investigated dmesg and queried all the error messages.

The root file system seemed to be corrupted by uncertain reasons.
Freshly flash the OS image (a link in my previous reply) into your eMMC.

Do you have an emmc-to-microSD adapter for flashing OS image?

I do not have an emmc-to-microSD adapter. Can I order an alternative via Amazon? I want it to arrive rather quickly so that I can perform this installation.

Can you show me a link to check if it is compatible or not?

It looks fine.

Also check a compatible card reader too.
