No credentials plugin in the Jenkins sidebar container and impossible to update

Question

I have some trouble with Credentials plugin in a fresh install of Jenkins inside a docker container.

First, I don't see it in the sidebar of the main menu but I can see it and administrate it via the plugins management.

Second, I have an error message in the update tab of the plugin management:

SSH Credentials: This version of the plugin exists but it is not being offered as an update. This is typically the case when plugin requirements, e.g. a recent version of Jenkins, are not satisfied.

Impossible to update.

Just in case because it seems to be retated to my error, I have a second message:

SSH Build Agents: This version of the plugin exists but it is not being offered as an update. This is typically the case when plugin requirements, e.g. a recent version of Jenkins, are not satisfied.

So in facts, I can connect a job to a public github repository but impossible tu use a ssh key with credential to do the same in a private repository...

Do you know how I can solve this?

Answer 1

So, in facts, the problem was due to different problem during the different updates process. After three update, everything is fine!
