I edited the /etc/fstab file per some instructions that cause my RPi5 to die. It doesn't boot to a usable screen at all, just a "you're in emergency mode...hit enter to continue." I hit enter and it displays the same message.
So, first thought, I pulled the SD card, dropped it into a reader and hooked it up to my RPi4. I can see the rootfs directory tree and can navigate it. I CANNOT edit the fstab file. I get an input/output error. I also get the same error when I try to access other directories like /var/spool. I'm sure it's a permissions issue, but the chown commands display the same error even with sudo.
A permissions error would be reported as such.
For more help I suggest you post:
- How you're mounting the root partition (no, in a card reader isn't what I mean)
- How are you viewing and navigating the directory tree?
- The exact command(s) you're using to edit the file
- The exact error message(s) you're getting.
- What you're using to power the 4B and whether you have any power hungry devices connected to it.
- Whether the card reader is directly connected to the Pi or via a USB hub.
