Cannot initialize bridge

[mmaderic]

Both Ubuntu 20.04 and CentOS 7.6 are stuck while trying to initialize using:

docker run --rm -it -v protonmail:/root shenxn/protonmail-bridge init

Both server instances are fresh deployments on DigitalOcean cloud provider.

[dev@centos-s-1vcpu-1gb-ams3-01 root]$ docker run --rm -it -v protonmail:/root shenxn/protonmail-bridge init

this is where it gets stuck and doesn't move after this point. Waited for more than 10 minutes without results.

Had the same issue.

This post gave me a workaround. Kill the two processes, run init, and continue as normal.

Seems you have problem generating gpg key. Try solutions here https://serverfault.com/questions/471412/gpg-gen-key-hangs-at-gaining-enough-entropy-on-centos-6.

For anyone out there who still has this issue, you can get around this by installing rng-tools. I'm running ubuntu, so installing it was as simple as sudo apt-get install rng-tools followed by sudo service rng-tools start.

Running the init command afterwards instantly resolved the issue.
