Hello @martti.laiho !

Writing tutorials for DBTechNet sounds fantastic. Please share anything

And, of course, we'd be happy to help however possible.

Hello Andreas,
Thank you very much for your email! Our consortium consists of RDBMS oriented teachers, and Neo4j is new to most of us.
Currently we have working 3.5.8 version installed in Debian 10 Linux VMs, but now outdated.
I have tried to replace it with 5.6.0 community edition, and managed to get Cypher working with APOC library.
However, Neo4j Browser is not working, and help on this issue is most welcome.
Best regards
Martti Laiho

Hi @martti.laiho ,

Could you elaborate on the issue with Neo4j Browser? Is it not loading at all? Or failing to connect to the database? Or something else?

Best,
ABK

Hi Andreas,
Please find attached my experiment on installing Neo4j 5.7.0 Community Edition into a fresh new Debian10 VM.
When I try to start the Neo4j Browser nothing happens as you can see at the end of the attachement

Best regards
Martti

Really strange. Could be some web browser incompatibility that was introduced, but then I'd expect some errors in the console.

I'll try to replicate the conditions.

Hi Andreas,

Now the CLI app seems to work fine, but on the terminal window in which I started it, it connects to dist.neo4j.org every 30 seconds to check the ../win/latest.yml for updates, for example
[12:45:54.819] [info] Graph App[neo4j-browser-id]: Checking 5.6.0 for suitable desktop API version

[12:46:00.712] [info] Online check request: https://dist.neo4j.org/neo4j-desktop/win/latest.yml

How can I get stabilized and how I should start it?

Best regards

Hi Andreas,
Looking at Neo4j Desktop dokumentation I noticed that it requires Deban 11.
