Encryption not available on this event-machine (with fix)

[alessandro-newzoo]

Hello,

I've just installed deployhq on a remote Debian machine I use for development, and I was get this error when trying to deploy:

Waiting for an available deployment slot...terminate called after throwing an instance of 'std::runtime_error'
  what():  Encryption not available on this event-machine
[1]    495531 abort (core dumped)  deployhq deploy

Ruby version:

ruby 2.7.4p191 (2021-07-07 revision a21a3b7d23) [x86_64-linux-gnu]

Steps to reproduce:

apt update

apt install ruby-full

gem install deployhq

deployhq configure

deployhq deploy

then I enter the number of the server I want to deploy to, and the error pops up after I press Enter:

How I managed to fix it:

apt install libssl-dev

gem uninstall eventmachine

gem install eventmachine

Conclusion

I don't know whether this is an issue specific to my setup or if there's something wrong with deployhq - either way I thought I'd post it here for those who run into this issue, and for the devs in case it can be fixed.

Cheers!

It's only been 9 months, no pressure guys :)

I'm sorry, but I am unable to reproduce this issue on an Ubuntu host with Ruby 2.7.4 installed via rbenv. It appears that installing the libssl-dev package may have resolved the problem for you.
