keyring | basic usage of keyring

I want to install packages from poetry.lock file; using poetry install.

However, the majority of packages throw the exact same error, indicating a shared fundamental problem.

What is causing this? What is the standard fix?

Specification:

• Windows 10,
• Visual Studio Code,
• Python 3.8.10 & Poetry 1.1.11,
• Ubuntu Bash.

Terminal:

• rm poetry.lock
• poetry update
• poetry install

I have a problem installing docker on my virtual machine. I have followed the steps below:

1. Older versions of Docker were called docker, docker.io, or docker-engine. If these are installed, uninstall them:

sudo apt-get remove docker docker-engine docker.io containerd runc

2. Update the apt package index

sudo apt-get update

3. install packages to allow apt to use a repository over HTTPS:

I was installing elasticsearch following this guide, but elasticsearch is not really the part of this question.

In the first step, I need to add the key:

I try to use library cv2 for changing picture. In mode debug I found out that problem in function cv2.namedWindow:

I'm trying to build a class in C++ using the QT framework that can inherit from QWidget.

I am attempting to do this by building an AbstractContent class in a header file that implements QWidget. Then, HorizContent inherits from AbstractContent.

The objective is to have multiple types of "content" all inherit from AbstractContent so that another class can "hot swap" the type of content it is displaying by simply redefining a single variable.

I am getting Linker errors with the code in it's current state. The code seems to compile just fine - the build fails when it gets to step: [build] [46/46 100% :: 137.186] Linking CXX executable spotify-qt

I have a Python 3 application running on CentOS Linux 7.7 executing SSH commands against remote hosts. It works properly but today I encountered an odd error executing a command against a "new" remote server (server based on RHEL 6.10):

encountered RSA key, expected OPENSSH key

Executing the same command from the system shell (using the same private key of course) works perfectly fine.

On the remote server I discovered in /var/log/secure that when SSH connection and commands are issued from the source server with Python (using Paramiko) sshd complains about unsupported public key algorithm:

userauth_pubkey: unsupported public key algorithm: rsa-sha2-512

Note that target servers with higher RHEL/CentOS like 7.x don't encounter the issue.

It seems like Paramiko picks/offers the wrong algorithm when negotiating with the remote server when on the contrary SSH shell performs the negotiation properly in the context of this "old" target server. How to get the Python program to work as expected?

I'm trying out Github codespaces, specifically the "Node.js & Mongo DB" default settings.

The port is forwarded, and my objective is to connect with MongoDB Compass running on my local machine.

The address forwarded to 27017 is something like https://.githubpreview.dev/

I attempted to use the following connection string, but it did not work in MongoDB compass. It failed with No addresses found at host. I'm actually unsure about how I even determine if MongoDB is actually running in the Github codespace?

When we launch substrate-front-end-template, the first thing one sees is a bunch of dummy accounts with some Balance, and I was under the impression that these accounts were being fetched from Genesis storage of the running chain. However, when I went into chain_spec.rs file and deleted all accounts, and even renamed some in the testnet_genesis function, I continue to see accounts, albeit with zero balance:

On the console, keyring.getAccounts() returns these very accounts.

Here's what my ChainSpec looks like :
