Error when pushing to GitHub repository from Jenkins - cannot use Git Publisher

Question

I am trying to push to a GitHub repository from Jenkins using

git remote set-url origin git@github.com:$reponame.git
git checkout $branch
git add file
git commit -m "Add file"
git push origin $branch

However I am getting the error:

ssh: /opt/bitnami/common/lib/libcrypto.so.1.0.0: no version information available (required by ssh)
ssh: /opt/bitnami/common/lib/libcrypto.so.1.0.0: no version information available (required by ssh)
Host key verification failed.

All the answers I've seen for solving this recommend using the Git Publisher Post Build Step. I am not able to use Git Publisher as I have multiple SCM defined which are defined by the $reponame variable.

I tried looking at the output of git show-ref and this shows the list of branches that are part of the GitHub repo.

I'm not sure how to solve the above errors, any help on this issue would be greatly appreciated.

UPDATE: I've been able to successfully push, however the changes are not reflected on the GitHub branch. When I check GitHub the commit is not added to the branch. When I run the job again, the push returns "Everything up to date" implying that the branch that it pushed to already has those changes.
Where is this Git push pushing to? And why are the changes not reflected on the remote GitHub branch?

As mentioned here, for a bitnami.com environment:

Could you please try to run source /opt/bitnami/use_jenkins before configure your Git repo in Jenkins: it will load all the needed env vars that you need.

If you're usng a LAMP Stack, the script you're looking for will have the name /opt/bitnami/use_lamp

Please note that the name of this script has the name use_APPNAME.
Depending on the Bitnami Stack you're using the placeholder APPNAME will be changed with the name of the app.

Also, double-check the nature of your SSH key (new OPENSSH format or old openssl PEM format)

I would use Jenkins pipelines or Multibranch which allows you push in your repo without using the GitHub Publisher plugin. You have to create a Jenkinsfile in your repo and create the job follow the documentation. Then you have to options:

SSH as you are doing:

    stage('Preparation') {
        // Get some code from the branch sending the webhook in GitHub 
        git 'your git repo'
    }

    stage('Build') {
        // Do some stuff here
    }

    stage('Push') {
        // Commit and push with ssh credentials
        sshagent (credentials: ['your credentials']) {
            sh "git commit -am 'Commit message'"
            sh 'git push origin HEAD:<yourbranch>' 
        }
    }

HTTPS as another response is suggesting:

    stage('Preparation') {
        // Get some code from the branch sending the webhook in GitHub 
        git 'your https repo'
    }

    stage('Build') {
        // Do some stuff here
    }

    stage('Push') {
      // Commit and push with ssh credentials
      withCredentials(
       [string(credentialsId: 'git-email', variable: 'GIT_COMMITTER_EMAIL'),
        string(credentialsId: 'git-account', variable: 'GIT_COMMITTER_ACCOUNT'),
        string(credentialsId: 'git-name', variable: 'GIT_COMMITTER_NAME'),
        string(credentialsId: 'github-token', variable: 'GITHUB_API_TOKEN')]) {
           // Configure the user
           sh 'git config user.email "${GIT_COMMITTER_EMAIL}"'
           sh 'git config user.name "${GIT_COMMITTER_NAME}"'
           sh "git remote rm origin"
           sh "git remote add origin https://${GIT_COMMITTER_ACCOUNT}:${GITHUB_API_TOKEN}@yourrepo.git > /dev/null 2>&1"                     
           sh "git commit -am 'Commit message'"
           sh 'git push origin HEAD:<yourbranch>'
        }
    }

I had problems while cloning and pushing/pulling with ssh once so i made it work by using HTTPS where it asks for my github passwords once like you can see in attached image and can use that HTTPS version URL to remotely add. This will make it work i believe but this isn't actual solution to your problem and SSH thing should work too. I just gave my alternate solution in case you're stuck in something like urgent work.
