Problem installing Java Installer on Synology NAS

[nickleigh78]

Hello,

Thanks for the reply. I added the Rednoah Java & FileBot Repository to DSM Package Manager (https://get.filebot.net/syno/) a long time ago, probably around Java 17 on this NAS, and added the Java Installer package. As far as memory serves, it was a rednoah developer and rednoah publisher but now it is not....

I have uninstalled the package and will wait for your response regarding the output of

Many thanks.

https://get.filebot.net/syno/ is our package repository. You seem to have added a different package from a different package source that uses the same name. You seem to have installed software for the https://spk7.imnks.com/ package repository, which seems to have java-installer packages that are based on our official package but with modifications for users in China.

UPDATE

[Synology] Java Installer fails to update: ghproxy.cfd DNS error (curl: Could not resolve host)

[nickleigh78]

As highlighted in [Synology] Java Installer fails to update: ghproxy.cfd DNS error (curl: Could not resolve host), once i removed the "https://synopackage.com/repository/spk/All" package source, i was finally able to reinstall the offical rednoah Java Installer package on DSM for a user outside China.

I'm sorry to inform you that I am also experiencing the problem mentioned below.

Currently having an issue with the Synology Java installer (23) on Synology DSM 7.2.2-72806 Update 5
DSM update was automatically installed overnight
Checksum mismatch and curl resolve host error in the install-java.log

Please could you provide any advice to fix the error.

Many thanks

This problem has been solved. The root cause is adding a 3rd party package repository that uses the same package ID as the official packages from our official repository.

Please read the posts above for details.

I don't have this package repository installed and never had.

[rednoah]

I don't have this package repository installed and never had.

Then the issue you have is not the issue discussed on this thread.

What does the log say?

If the log says Could not resolve host: ghproxy.cfd then you most assuredly are not using our java-installer package. If the log says something else, then it's a different issue.

But you're getting an SSL error:

Unfortunately, since I cannot reproduce the issue, you'll have to figure it out from there yourself from your end. The gist is simply that your NAS fails to download that file. If you SSH into the NAS and try to do it manually step-by-step, you might be able to figure something out, some technical expertise required though.


SSL certificate problem: unable to get local issuer certificate might indicate that your NAS is very out-of-date and doesn't have the current common root certificates required for HTTPS connections. That's just a random guess though. Could be something else entirely.

[Linus]

Thank you very much!

What makes me wonder is that I didn’t have any problem installing the Java installer at first. But then, all of a sudden, it stopped working, and the package showed “Repair.” Now I can’t reinstall it anymore.

[rednoah]

SSL certificates expire and get renewed all the time. It's very possible for something to work last year / month / week and not work this year / month / week.
