Openssl: command not found

GitLab CI/CD
#1

My build keeps on sporadically failing with:
/bin/bash: line 98: openssl: command not found

I am using GitLab CI to run a test build using SFDX (Salesforce Developer Experience), but even before I am able to do anything the script fails! This doesn’t happen every single time and there is no correlation between what I am committing and this error being thrown.

It is literally the first line :man_facepalming:, does anyone have any idea why this could be failing?

The only workaround I have found at the moment is to go to “Pipelines” > “Run Pipline” > select Merge Req > “Run Pipeline”. This is probably happening with 2/5 commits.

Below is the start of my script (there is a lot more after this).

#
# Download the Salesforce CLI and install it
#
before_script:
  # Decrypt server key
  - openssl enc -nosalt -aes-256-cbc -d -in assets/server.key.enc -out assets/server.key -base64 -K $DECRYPTION_KEY -iv $DECRYPTION_IV

  # Set up environment variables
  - export CLIURL=https://developer.salesforce.com/media/salesforce-cli/sfdx-linux-amd64.tar.xz  
  - export SFDX_AUTOUPDATE_DISABLE=false
  - export SFDX_USE_GENERIC_UNIX_KEYCHAIN=true
  - export SFDX_DOMAIN_RETRY=300
  - export SFDX_DISABLE_APP_HUB=true
  - export SFDX_LOG_LEVEL=DEBUG
  - export DEPLOYDIR=src
  - export TESTLEVEL=RunLocalTests

  #Create sfdx directory
  - mkdir sfdx

  #Install Salesforce CLI 
  - wget -qO- $CLIURL | tar xJ -C sfdx --strip-components 1
  - "./sfdx/install"
  - export PATH=./sfdx/$(pwd):$PATH

  # Output CLI version and plug-in information
  - sfdx --version
  - sfdx plugins --core

I need to decrypt the encrypted server key to be used in a JWT Auth Flow using SFDX
