I received a scary email from noreply@letsencrypt.org mentioning I should update my ACME client as TLS-SNI-01 validation is reaching end-of-life. Unfortunately the guy who setup our server environment is no longer available and I don’t have any clue how to resolve this update request.
I followed the suggestions in the mail and followed How to stop using TLS-SNI-01 with Certbot as we are using certbot. First step in this tutorial is to check the certbot version using certbot --version. Turns out certbot version is certbot 0.19.0. I am on a aws ec2 instance ubuntu-xenial-16.04-amd64.
As the version is too low I try to update by going to https://certbot.eff.org/ I fill out my software (Nginx) and system (ubuntu 16.0.4) and i get forwarded to a page on how to install certbot. However, I am not interested in installing certbot, I need to upgrade it. I googled and found that sudo apt-get install certbot should be run to resolve. However the output is:

You might want to run 'apt-get -f install' to correct these:

libstdc++6 : Depends: gcc-5-base (= 5.4.0-6ubuntu1~16.04.9) but 5.4.0-6ubuntu1~16.04.11 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
I try to resolve by running apt-get -f install and then get
E: dpkg was interrupted, you must manually run ‘sudo dpkg --configure -a’ to correct the problem.
Then I run sudo dpkg --configure -a and then the process just hangs at

Stuck. I am a noob regarding this kind of topics and have no idea how to further proceed from here and prevent my SSL certificate become outdated
Any help greatly appreciated.
Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
