Running an old wrt tomato release on my wifi AP. Today, after upgrading to fedora 23 some weeks ago, I wanted to ssh to it for a reboot. Got the above error message. Well, there is a fallback method – to enable this obsoleted algorithm it seems.

ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 user@host

Upgrade to fedora 23 and nvidia problems

Filed under: ComputerStuff_en — Thalamus @ 14:55

So, once again I had troubles after updating to a new kernel / nvidia-modules and fedora in general. Update went as planned, except when gnome where supposed to start … it just gave me a blinking text screen and it became very hard to even write anything to the console.

So, I booted up the machine into runlevel 3 ( pressed b during boot – and added a ‘3’ to the kernel line followed by ctlr-x )

Once in runlevel 3 – I uninstalled all the nvidia drivers. I first checked what would be removed by issuing a ‘dnf remove \*nvidia\* 2>1 1>/tmp/wtf’ … this because the screen in runlevel 3 wasn’t big enough …

Well, uninstalled all ‘dnf -y remove \*nvidia*\’ – reinstalled it again with ‘dnf install akmod-nvidia kernel-devel’ … then ran ‘systemctl restart akmods’ – ran ‘systemctl restart gdm’ and I was back up and running again.

Next step – added ‘exclude=kernel* akmod*’ to /etc/dnf/dnf.conf … I can live without most kernel upgrades that comes with fedora. If not – well, then I hope this post might help me next time around.
