Observation¶

On Leap 15.4, with python-paramiko 2.4.2-150100.6.12.1, following occurs in mtui:
info: connecting to goblin.qam.suse.cz
debug [mtui.connection:connect]: connecting to goblin.qam.suse.cz:22
error: SSHException while connecting to goblin.qam.suse.cz

paramiko.ssh_exception.SSHException: Invalid key


This seems to be a known issue, and is resolved in paramiko 2.5.1. As usage of ed25519 keys is not that common it seems to affect only me, as a workaround paramiko from Tumbleweed can be linked into QA:Maintenance project in IBS

Same problem in Leap 15.3 as paramiko was last updated in 15-SP1.

Acceptance criteria¶

• AC1: Problem has been reported to the package maintainer
• AC2: mtui works again

Suggestions¶

Maintenance Update of paramiko in SLE -> Leap

Link new paramiko and its deps in QA:Maintenance project
