net-ssh | Pure Ruby implementation of an SSH client

I'm trying to deploy my Ruby app using capistrano (repository is on gitlab) and I get this error:

I am re-installing vagrant on my local machine unsuccessfully. Initially, I had vagrant downloaded, installed and running well, but decided to uninstall it. My uninstall was as follows:

I am using rbenv and bundler on macos.

I need to maintain multiple versions of Ruby for my application. Specifically 2.2.4 and 2.5.5. Different users will have different versions.

Currently I am only working with 2.2.4 so I do the following. My gemfile looks like this

this is my first attempt to deploy a Rails app using Capistrano. I am following the tutorial at https://ogdenstudios.xyz/blog/how-do-i-deploy-a-rails-6-app-to-amazon-ec-2/ to deploy to an AWS EC2 instance. My app is on Rails 6 and runs smoothly on localhost. I followed the tutorial but I am stock in the final step, when i run cap production deploy y get the following error:

I picked up a 4 year old project written in Ruby 2.1.3 and Rails 4.1.8.

Very few of the gems were versioned but I've managed to get the project running locally by installing mysql2 0.3.20 as suggested in multiple other threads. Doing this required me to (on MacOS) downgrade openssl and mysql with brew install mysql@57 and brew install openssl@10.

I could then install mysql2 with by passing the correct libraries to it: gem install mysql2 -v 0.3.20 -- --with-mysql-config=/usr/local/opt/mysql@5.7/bin/mysql_config --with-ldflags=-L/usr/local/opt/openssl@1.0/lib --with-cppflags=-I/usr/local/opt/openssl@1.0/include

Everything works locally, all good.

I'm trying to deploy this project with Dokku on a Debian instance. Here's the readout from the push to dokku master including the error thrown when starting the Rails server:

I am using rails "v6.0.2.2". I am following a gorails tutorial to deploy a rails 6 app to a digital ocean droplet using the following gems. Also note I am not using his app from the tutorial I made my own.

• gem 'capistrano', '~> 3.11'
• gem 'capistrano-rails', '~> 1.4'
• gem 'capistrano-passenger', '~> 0.2.0'
• gem 'capistrano-rbenv', '~> 2.1', '>= 2.1.4'

When I run cap production deploy it hangs up on,

I am currently working on a Ruby script which is supposed to perform different tasks on a pretty long list of hosts. I am using the net-ssh gem for connectivity with those hosts. The thing is, there seem to exist some conditions under which net-ssh times out without throwing an exception. As of know, the script was only once able to finish a run. Most of the time, the scripts just hangs at some point without ever throwing an exception or doing anything.

I thought about running all tasks that may timeout in different threads, passing them a pointer to some variable they can change when the tasks finished successfully, and then check that variable for a given amount of time. If the task has not finished by then, throw an exception in the main thread that I can catch somewhere.

This is the first time I am writing something in Ruby. To give a clear demonstration of what I want to accomplish, this is what I'd do in C++:

I'm trying to deploy a Rails 6 app with Capistrano + Nginx + Puma. In the past(Rail 4 in that case) I used this tutorial https://www.digitalocean.com/community/tutorials/deploying-a-rails-app-on-ubuntu-14-04-with-capistrano-nginx-and-puma and it worked fine.

However, when I try to run cap production deploy:initial(or without the initial namespace) I receive the following error: The deploy has failed with an error: Exception while executing on host 31.220.51.222: Exception while executing on host 31.220.51.222: corrupted hmac detected ** Invoke deploy:failed (first_time) ** Execute deploy:failed

So I'm not sure if it is a problem with NET::SSH and where it comes from, or if it is a problem that have nothing to do with this message.

Following is the last lines of capistrano.log with the -t option enabled.

I'm using Laravel 7.x Homestead. Everything had been working fine for years, maybe until around the time I upgraded from 6.x to 7.x (though I'm not sure because I don't frequently try to reload).

Now whenever I run cd /c/code/Homestead/ && vagrant up or cd /c/code/Homestead/ && vagrant reload --provision this happens:
