Python3 - robotframework-sshlibrary throws serialization.Encoding.Raw error
Hi Jamo,
For the Gerrit: https://git.opendaylight.org/gerrit/c/integration/test/+/90617 (Fix python3 issues in Netvirt )
- I was able to get pass logs without warnings for Upgrade script.
- But for the job: srini-netvirt-csit-1node-0cmb-1ctl-2cmp-openstack-rocky-upstream-stateful-itm-direct-tunnels-magnesium
- The script is failing during the SSH connection.
- It is seen that first time SSH connection gets established, while the next time it fails with below error message:

I think this issue is with robotframework-sshlibrary( 3.1.1)and with cryptography dependency.

I could not find a solution or fix for this and need help on this.
Thanks,

Hi Jamo,
I have raised the below review:
https://git.opendaylight.org/gerrit/c/releng/builder/+/90806
The issue is :- paramiko 2.7.1 has requirement for cryptography>=2.5
Thanks,
