I tried neo4j 3.0 on two machines.
Had a working neo4j 2.x and upgraded to neo4j 3.0 through apt-get upgrade
Fresh installation of neo4j 3.0
In both cases, neo4j does not start and I see the following error message
[console]
sudo service neo4j start
Job for neo4j.service failed. See 'systemctl status neo4j.service' and 'journalctl -xn' for details.
$ sudo systemctl status neo4j.service -l

since last week, I am unable to set up a TLJH Development Environment as described here:
https://tljh.jupyter.org/en/latest/contributing/dev-setup.html.
Up until January 23 2023 the process went smoothly, but after rebuilding the image last Friday (27 January), after running bootstrap.py in the container, the server doesn't spawn. Browsing to my localhost:12000 I just see the message "404 page not found".
I am running TLJH in a container in an Ubuntu 22.04 host, running Docker version 20.10.21.
On the same host, when using the image I build before January 23 with the same method I can spawn the server ok. There were no new commits on the TLJH repo since, so the issue should not be there.
Here is the output of journalctl -u jupyterhub -f ran inside the container:

Since the logs show an error in sqlalchemy, I tried dowongrading sqlalchemy from 2.0.0 to 1.4.46, and then reloaded the hub, but that didn't solve the problem
Is anyone else experiancing the same issue? Any ideas for further troubleshooting?
Thanks!
EDIT: I applied the solution described here and it worked.
Commands to run:
pip3 install --upgrade 'SQLAlchemy<2.0.0'
tljh-config reload hub
I applied the solution described here and it worked.
The reason seems to be an issue introduced in SQLAlchemy 2.0.0, is resolved by downgrading SQLAlchemy.
Commands to run:
pip3 install --upgrade 'SQLAlchemy<2.0.0'
tljh-config reload hub
in the logs the following information

Tried to update Jenkins as after the same error the first time it worked
and I also tried changing the Jenkins config and setting the version:
openjdk version "1.8.0_352"
OpenJDK Runtime Environment (build 1.8.0_352-8u352-ga-1~20.04-b08)
OpenJDK 64-Bit Server VM (build 25.352-b08, mixed mode)
the problem was that the new version of django does not support version 8 of java
this command caused a problem when starting jenkins:
journalctl -f --unit=jenkins
next, I'm just install java11:
sudo apt install openjdk-11-jdk
and change default java,
sudo update-alternatives --config java
after this command choice java version by number
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 to keep the current choice[*], or type selection number: 0
next, start jenkins
systemctl start jenkins.service
I am having trouble with my docker installation.
I rent a arm storage server for my setup.
The kernel is
4.5.2-armada375 #1 SMP Tue Oct 25 11:52:56 CEST 2016 armv7l
But when i try to insall docker-ce and the other packages ive got the following error:
Jul 09 20:54:50 storage-fr systemd[1]: Failed to start Docker Application Container Engine.
Jul 09 20:54:50 storage-fr systemd[1]: docker.service: Unit entered failed state.

Setting up aufs-dkms (4.9+20161219-1) ...
Loading new aufs-4.9+20161219 DKMS files...
It is likely that 4.5.2-armada375 belongs to a chroot's host
I think the kernel is not compatible.
IS it possible to install docker on it?
I tried this guide https://docs.docker.com/install/linux/docker-ce/debian/
But it doesnt work.
Any idea ?
Trying to upgrade local Neo4j instances and getting errors on start.
Ubuntu 16.04: Trying to upgrade local instances of Neo4j databases which are currently at 3.3.1.
Installed Neo4j Desktop thinking I could do it with that and found the lowest version it upgrades from is 3.4. I now can't remove that. Ubuntu software fails (I just click remove, restart and Neo4j Desktop is still there). dpkg --list doesn't list neo4j desktop, so I can't use "apt-get remove" to remove it.
Uninstalled 3.3.1 and installed 3.3.9 (latest version of 3.3.x). Started Neo4j and ran fine, updating the database stores to 3.3.9.
Uninstalled 3.3.9 and installed 3.5.7.
Expecting Neo4j to start normally with "sudo service neo4j start", but now getting the following:

Checked that I am running JVE 1.8:
openjdk version "1.8.0_212"
OpenJDK Runtime Environment (build 1.8.0_212-8u212-b03-0ubuntu1.16.04.1-b03)
OpenJDK 64-Bit Server VM (build 25.212-b03, mixed mode)
Unsure how to proceed. Any ideas welcome please. Thank you!
Found the answer by running "journalctl -e -u neo4j" to view the full error log. Turns out that it was an APOC jar that was installed for 3.3.x but not compatible with 3.5.x. Removing the jar file solved it.
I have installed neo4j on Debian 8.1 thanks to these instructions : http://debian.neo4j.org/
Now if, as root, I start neo4j with neo4j-service like this
service neo4j-service start
Sometimes it will works correctly but most of the the time, the neo4j-service will timeout. But the interesting fact is that neo4j is indeed started, I can go the the browser and make some queries. But the neo4j-service tells me that it failed :
root#ns***:~# service neo4j-service start
Job for neo4j-service.service failed. See 'systemctl status neo4j-service.service' and 'journalctl -xn' for details.

And sometimes it will tell me that the service started correctly but will not manage to stop it.
Most of the time, I have to kill the process myself to "reset everything" correctly.
Do you know why this is happening ?
Are you aware of any issues with the neo4j-service on Debian 8.1 ?
This approach to running Neo4j is deprecated and you should use neo4j command.
Or you can write your own service wrapper and for that I suggest to you use http://supervisord.org/
