I can test this later today

I already installed geonode 2 times on ubuntu 20.04LTS. For me, installation of geonode in 18.04 also works fine.

@afabiani Thanks. This is a great step forward! I've gone through the changes and haven't found anything. Unfortunately I won't find time to do a test install before Monday. It would be awesome if you @gannebamm could do a test install?!

[afabiani]

@t-book @gannebamm I wrote those changes by following a new setup from scratch on a brand new WSL2 Ubuntu 20 instance on Windows 10

Nevertheless, it would be good that you could find some time to go through the steps and see if I missed something.

We don't want users getting angry with us anymore (hopefully)!

Well true, but one should never forget that we all invest a lot of voluntary work ;)

This might be connected to not run too often in outdated links : #57

[afabiani]

@t-book I tried to mitigate that issue here

https://github.com/GeoNode/documentation/pull/64/files#diff-f997ec698d6807d12b7b6b0e377d2466461b84c54b764bb7ccef227d50c174b0R386

It works but throws some errors / warnings. Some may be related to my virtualization software (hyper-v). I installed it up to paver setup/sync/start and uploaded a ~20mb shapefile successfully. Here are my findings:

geonode@geonode-Virtual-Machine:~$ sudo add-apt-repository ppa:ubuntugis/ppa
E: The repository 'http://ppa.launchpad.net/ubuntugis/ppa/ubuntu focal Release' does not have a Release file.

I think we can safely ignore this.

geonode@geonode-Virtual-Machine:~$ sudo update-java-alternatives --jre-headless --jre --set java-1.8.0-openjdk-amd64
update-alternatives: error: no alternatives for policytool

I encounter this all the time and up to now never had issues related to it. What do you guys say @afabiani @t-book

on layer upload:

I think both are also not critical, since the upload worked and the thumbnail was created.

I now have to switch to some other tasks, but if I shall also test the rest of the setup, drop me a line here and I´ll come back to it later.

[afabiani]

@gannebamm those errors are normal when using SQLite. They will disappear with postgis.

There's a big warning for that on the docs.

Use sudo update-alternatives --config java command to show available java configs. The output is as below in Ubuntu 18.04.

There are 2 choices for the alternative java (providing /usr/bin/java).

  Selection    Path                                            Priority   Status
------------------------------------------------------------
  0            /usr/lib/jvm/java-11-openjdk-amd64/bin/java      1111      auto mode
  1            /usr/lib/jvm/java-11-openjdk-amd64/bin/java      1111      manual mode
* 2            /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java   1081      manual mode

Press <enter> to keep the current choice[*], or type selection number:

In this case number 2 is the default (indicated by the asterisk). If not type the number and click enter on your keyboard. I hope this information helps. I would propose we add this in the documentation as the previous command shows error
