I installed CCM utility of Cassandra, but when I try to create a cluster with the following command:
root#ubuntu2:~# ccm create cluster1 -v=2.0.9
I get the following error:
Traceback (most recent call last):

ccmlib.common.ArgumentError: Invalid version =2.0.9 (underlying error is: HTTP Error 404: Not Found)
Changing to any other version of Cassandra in the command does not help.
There is no issue with Internet connection.
Will appreciate help.
Try ... -v 2.0.9
As the error suggests, the version number '=2.0.9' is not valid.

I am trying to run a simple lambda function using AWS sam, version(1.57.0)
I've installed in my ubuntu system nodejs version 14.18.3
When I try to run the project it gives errorUnsupported Lambda runtime nodejs18.x
Below is the full stacktrace

I did have node version 18 installed in the system prior to this. I thought that may be giving the issue so I uninstalled that version and installed version 14.
I don't have any idea why sam is running it on node version 18
I just recently looked into this as well since Node 18 is the current LTS. If you go to the Serverless Image Repository you'll see that AWS SAM doesn't currently have an image for Node 18. There's an explanation about this in this Github issue.
Environment(s)
Ubuntu 20.04 & Debian 10 with Python 3.8 or 3.7, respectively.
Postgresql versions 11, 12, and 14 have been tried.
Psycopg2-binary 2.8.6
Overview
I'm attempting to install a Django project, and I'm getting this error:
psycopg2.errors.UndefinedFile: could not open extension control file "/usr/share/pgsql/extension/citext.control": No such file or directory
The psycopg devs informed me this is likely an issue with the postgresql-contrib libraries. Similarly, others have been able to fix this error by installing postgresql-contrib, however, this does not work for me. I've also tried installing postgresql-12.
I can see that citext.control is available in /usr/share/postgresql/12/extension/citext.control, so I tried ln -s /usr/share/postgresql/12 /usr/share/pgsql with no effect.
I also ran CREATE EXTENSION citext; in Postgres, also without effect.
Any support with this would be greatly appreciated, as I was hoping to have this project live already!
Thanks so much.

Have you tried installing python3-psycopg2 from the packaging system instead?
My Ubuntu 20 setup has this installed, and postgresql connections work with django.
ii python3-psycopg2 2.8.4-2 amd64 Python 3 module for PostgreSQL
I had installed postgresql-contrib on the local django server rather than the remote DB server. Installing on the same server as Postgresql resolved the issue.
I want to start my docker-compose and I always get this error.
Docker Desktop tells me I'm logged in. I also rebooted once and logged in again.
I don't quite understand why that's not possible. If I pull other Docker Containers in another project, everything works.
We dont use paython in our project.

resetting the docker in docker-hub/settings solved the problem.
I am new to Python and trying to install Airflow in my Mac, by following this tutorial
While these two commands work fine:
$ airflow initdb
$ airflow webserver -p 8080

EDIT: Python 3.8 is supported now https://github.com/apache/airflow#requirements. So this answer might not be relevant now.
This due to the Python version you are using. Airflow doesn't support Python 3.8 yet https://github.com/apache/airflow#stable-version-1109.
Downgrade your Python to 3.7 and check.
Maybe there are some compatibility problems?
Using Python 3.6.10 and airflow v1.10.4, I can get airflow running. Maybe you could try some other versions?
This worked for me!
1- Make sure you are using the correct celery version that supports your other packages like RabbitMQ ( as V5 doesn't support AMQP in its usual format), my advice is to use V4.6.X
2-THIS HAS NOTHING TO DO WITH PYTHON VERSION IF YOU ARE USING AIRFLOW V2.0
3- simply make yourself happy with airflow db reset (command may differ if you are using airflow Version X<2.0 )
4- Avoid deleting any dag like you delete a file and use airflow dag ... commands to do so. (it makes up a mess in your environment that you wont like, trust me on this..)
Wish you luck bearing python stuff..
I followed the official vagrant-dcos instruction to install cassandra with minimal setup, by running command below, and got errors. Any idea?
dcos package install --options=examples/oinker/pkg-cassandra.json cassandra --yes
