Node did not start after updating Ubuntu, to 22

I upgraded the Ubuntu os to 22. , now the node does not start, and i got the error msg:

● cardano-node.service - Cardano Node Service
Loaded: loaded (/etc/systemd/system/cardano-node.service; enabled; vendor >
Active: activating (auto-restart) (Result: exit-code) since Sun 2023-04-23>
Process: 4694 ExecStart=/bin/bash -c /home/cardano/cardano-my-node/startCar>
Main PID: 4694 (code=exited, status=127)

Anybody knows, what to do ? I did try to start & reload the node

Best regards,

Check the guide provided by @tsipou

After a successful Upgrade

sudo systemctl status cnode
sudo systemctl stop cnode
cd .local/bin/
rm cardano-ping
rm mux-demo

cd tmp/
./ -sd

sudo systemctl restart cnode

enjoy evening!!!



Thanx!, I got error msg, directly unfortunatley, after typing command:

sudo systemctl status cnode

error msg:

Unit cnode.service could not be found.

Best regards,

What cou8d be the problem? I did try:

sudo systemctl restart cnode

error msg:

Failed to restart cnode.service: Unit cnode.service not found.

What do you mean with WA?

I did not do the upgrade from the terminal as in the guide. I got asked if I wanted to upgrade to Ubuntu 22. And I did answers yes, then I got asked if I wanted to keep the local version of chrony and sshd_config & I kept the local version of both.

Best regards,

If i am going to start rebuiilding the node, becouse of this, from where should i start?

I did type this command: journalctl -e -f -u cardano-node

error msg:

apr 24 06:14:17 nr-server cardano-node[41040]: /usr/local/bin/cardano-node: error while loading shared libraries: cannot open shared object file: No such file or directory

@poonasor provided a solution in the past

after doing a bunch of digging and searching on this forum and StackOverflow I finally found the solution.

for anyone who finds this post and needs a solution, here it is

sudo dpkg -i libssl1.1_1.1.1f-1ubuntu2.17_amd64.deb
