latest openSSH seems to be broken Kirkwood/ARMv5

Postby kurter » Wed Jul 22, 2015 4:43 pm

I hadn't done pacman -Syu for about a month on my 3 servers.
one of the packages to come down was openssh-6.9p1-1.
After the reboot everything worked BUT.... SSH. :twisted:

Thankfully, I had a serial console on one of my 3 servers.

I was able to access the cached older version openssh-6.8p1-3 by

pacman -U /var/cache/pacman/pkg/openssh-6.8p1-3-arm.pkg.tar.xz
(confirm the downgrade)
(wait)

then preventing updates to openssh (for now)

nano /etc/pacman.conf
add
IgnorePkg = openssh
save

now when you run pacman -Syu
:: Starting full system upgrade...
warning: openssh: ignoring package upgrade (6.8p1-3 => 6.9p1-1)

The good news, is that SSH can now be ignored (for now) and everything continues to work.

Does anyone have any ideas what is broken?

Perhaps an error message ?

"Its broken" does not help us at all.

After peforming pacman -Syu, my SSH stopped working as well. I could ping it but SSH would simply time out after a period of time, maybe a minute?

I'm using ALARM on a GoFlexHome.

I can connect the drive to another computer and try to get some log files. Is there a particular one to look for?

Clarifying my earlier statement.....

SSH is running as a visible process via the 'top' processes command.

Any attempt to connect to the SSH port (22) is met with no answer.

The other services running on the server continued to function.

I don't know where there would be 'error messages' shown.

Downgrade as noted above resolved the issue for me. :|

I just logged in to post the same issue and saw this thread.

Ping works, everything else works, can't connect to SSH after upgrade.

Any recommendation on how to fix this issue without SSH access or Serial? I have SAMBA and access to "/". Thanks

Anyone got a older online version of openssh package available?

I still have SSH access to one of my Pogoplug and would like to downgrade before I get disconnected. No package in the cache. Thanks

Ended up install a telnet server for now so at least I can connect.

Has anyone had a chance to look more into this issue?

SSH access is fairly important and currently if anyone does a "pacman -Syu" they'll lose it.

Thank you for testing @moonman. After your comment, I tested from my linux VM and was able to connect.

Looks like the issue is with Kitty/Putty from Windows. Here is error in the log. Haven't had a chance to investigate what it means yet though. Happy enough that I can connect.
