SSH Update issue Pi 1B+


#1

I ran sudo apt update then sudo apt full-upgrade on 2 OSMC Pi’s this morning.

The first one went with no issues, i seen it wanted a reboot when complete. ran sudo apt autoremove prior, it rebooted an I could ssh right back in.

The second one I preformed exact same tasks. However it would not let me ssh back in, connection refused. It pings and replies, I can use my Kore remote on androids to connect and control Kodi, just lacking my ssh connection. Connected a keyboard, EXIT, ESC at splash and get terminal, login with user osmc and pass osmc. Enter sudo raspi-config screen goes blank and then it reboots to Kodi.

What I’m looking for is what file to edit while the fs is mounted in a MicroUSB reader.

TIA
Bill

raspi-config doesn’t exist on OSMC.

Sam, what log would be relevant in the OSMC log uploader that when I ssh in from another system that says connection refused?


#4

Just use grab-logs -A than you can be sure to catch it.


#5

Entire Log “ALL”

Looks like you have a Pi1 not a Pi2 just for future reference.

Looks like your ssh setup is messed up.
Whats the output of ls -lah /run?

4USB ports were nto available on Pi 1 iirc. just a minute, I’ll have to go upstairs with laptop since ssh isn’t working :confused:


#9

Show URL of
paste-log /etc/ssh/sshd_config


#10

It’s a Pi 1 Model B+ revision 1.2


#11

Tried, as soon as I get logged into treminal, I typed out ls -lah /run and the system reboots to Kodi GUI.

I can mount the MicroSD card onto my ubuntu laptop if that would be beneficial to tracking this down


#12

btw I even went throught he My OSMC interface and disabled and reenabled sshd.service in Services menu to no avail.


#13

Thats not a good sign and actually quite confusing


#14

running update manually from My OSMC again, see if that helps anything


#15

If that doesn’t help remember


#16

Had to mount the card on my laptop to get it.
It looks like almost everything is commented out.

Why? What happend when you run paste-log /etc/ssh/sshd_config ?

But the sshd.config looks ok (I reformatted your post so it’s readable)


#18

#19

Even after you press ESC?


#20

I get logged in with osmc osmc type out command hit enter and it reboots
