I used the moment when Jenkins in the browser said to me, that I'm
offline and if I want to continue without updating the plugins. I
created an account and when I now update plugins manually, some work
fine, sometimes it fails with a message in the log file, like:
[2023-07-28 09:50:31][SEVERE][hudson.model.UpdateCenter$DownloadJob run] Failed
to install scm-api
java.io.IOException: Failed to dynamically deploy this plugin
at
hudson.model.UpdateCenter$InstallationJob._run(UpdateCenter.java:2204)
at hudson.model.UpdateCenter$DownloadJob.run(UpdateCenter.java:1850)
...
It even says sometimes in the browser (like right now) that the update
of a given plugin was successful, but that a test to Google.com failed:
Download progress
Preparation
Checking internet connectivity
Checking update center connectivity
Success
Failed to connect to https://www.google.com/. Perhaps you need to configure
HTTP proxy?
Mina SSHD API :: Core Downloaded Successfully. Will be activated during
the next boot
When I watch such a plugin update with tcpdump for all traffic to/from
port 443 such fetch is very slow and lazy. I looked in the file for
the update: the JSON file in https://updates.jenkins.io/update-center.json
it has 3413 URLs for downloading and I understand now why this took
always so long in the first initialization of Jenkins.
What should I do. Our IT department will say: 443 outbound is all open
...
Thanks
