SHA - Unable to confirm integrity of downloaded file

[sathomps]

I've updated my version of Jenkins to 2.131, using the juseppe-plugin and the update-sites-manager-plugin. When trying to install an internal plugin hosted and produced by the plugins above, I get the following error in Jenkins.

Attempt to verify a downloaded file (xxx.jpi.tmp) using SHA-512 failed since your configured update site does not provide this checksum. Falling back to weaker algorithms.
Jul 10, 2018 1:29:38 PM SEVERE hudson.model.UpdateCenter$DownloadJob run
Failed to install XXX
java.io.IOException: Unable to confirm integrity of downloaded file, refusing installation

[pcooke2002]

I am having this problem... is anyone else experiencing this? Do we have a fix? looks like they updated jenkins to require more stringent hash check

[sathomps]

The fix is actually pretty simple, I haven't had a chance to submit a pull request.

Hi thanks for posting this.
My employer prohibits me from modifying any OSS tools or contributing to any OSS source code.

[grazius]

hi all
this fix need to be integrated or juseppe will stay unusable with last version of jenkins.

[sathomps]

As it appears that this project is no longer being maintained, I'll create a fork this weekend with the update.

[lanwen]

yes, sorry, have no time to maintain it anymore, as don't use it by myself for a long time

[lanwen]

@sathomps actually you can send PR if you find a solution - will merge it

[sathomps]

Thanks @lanwen for the update, understandable with the time commitments.

As I need this tool at work, I'll take over the project if you don't mind?

[lanwen]

sure, I can give you write permissions

[sathomps]

Thanks!

[lanwen]

@sathomps done, but please always submit changes using PRs

[grazius]

@sathomps hello,
now you can add this fix ?
you can generate the docker hub image also ?

[lanwen]

docker hub image build automated from master and tags

[sathomps]

@grazius I will be incorporating this change on Sunday afternoon.

[sathomps]

Please reopen if you continue to have issues.

[grazius]

Nice thx
Can you also update the docker hub image with this fix?

[lanwen]

@sathomps
test failed for some reason
https://hub.docker.com/r/lanwen/juseppe/builds/bntmzmpx2tj6vxqml2jhgtu/

[sathomps]

Hmm - the tests on the merge said it was successful.

The logs referenced to the Docker build failed due to a timeout. How do you trigger a new docker build, not familiar with the process.

[lanwen]

You can turn off tests on package phase in pom

[sathomps]

Sure I know how to turn off tests in the pom but it's not really a solution :)

I'd like to trigger another travis build but it appears I don't have owner access to this repository - can't view settings.

[lanwen]

build is automated on docker hub side

[lanwen]

since issue exists only while docker build, i suggest to turn the tests off while creating the container - as it adds no value after PR and master are tested

[sathomps]

Docker build has been updated
https://hub.docker.com/r/lanwen/juseppe/builds/bgtw8cadyb6vn2dzdcpjudi/

[pcooke2002]

Hi when will there be a release that includes this code? I see it checked in some time back and no new release???

[sathomps]

Code is there and has been merged.

[caohhung]

Hi, latest release doesn't contain this fix https://github.com/jenkinsci/juseppe/releases

cc @lanwen

[vihoti]

Hi @sathomps
I am using v1.2.2 and for versions of Jenkins LTS >= 2.319.1 we are getting the same error message.
Should I open a new issue or does it suffice to mention it here?
