Hi,
we have just released updated modules for SNAP.
They fix issues with writing of data and with the product library.
The solved issues are listed in JIRA: SNAP 8.0.1 - JIRA

Thanks for the update! Everything worked fine when updating SNAP 8 on Windows using GUI but I am running into issues when trying to update in a Dockerfile based on Debian image:
RUN wget http://step.esa.int/downloads/8.0/installers/esa-snap_sentinel_unix_8_0.sh
RUN chmod +x esa-snap_sentinel_unix_8_0.sh
RUN ./esa-snap_sentinel_unix_8_0.sh -q
RUN /opt/snap/bin/snap --nosplash --nogui --modules --update-all
The update starts but later reports a java error (“No fonts found”) and restarts in never ending loop. The same method worked with SNAP 7. I am posting only a snippet of the output and stack trace:
Will update org.esa.snap.snap.unmix@8.0.0 to version 8.0.1
Will update org.esa.snap.snap.remote.execution@8.0.0 to version 8.0.1
Will update org.esa.snap.snap.ndvi@8.0.0 to version 8.0.1
Will update org.esa.s1tbx.s1tbx.op.calibration@8.0.0 to version 8.0.1

I’ve found that this is a known issue with the OpenJDK distribution by AZUL.
Using Fonts with OpenJDK / Zulu – Azul Systems
In this article it is suggested to install some fonts.
We should check if another JDK distribution would be better and does not have this issue.
Maybe AdoptJDK or Corretto. I’ve opened a ticket for this:
[SNAP-1367] Azul JDK does not include fonts - JIRA
Installing fonts fixed it, thanks

Hi, SNAP 8.0 update not working here. Can´t download plugins.
Error message “Unable to connect to the Update Center”, “The server maybe unavailable at the moment. Try again later.”.
I tryed so perform the update during all day.
Hello,
This can happen if you stumble upon a heavy traffic that overloads the server resources.
Also, there were some space issues on the server that now are solved.
Please let me know if it works now / worked eventually to perform the update.
Best regards,
Oana
