+- Upgrade CGSpace (linode18) to Ubuntu 18.04:
+  - Check any packages that have residual configs and purge them:
+  - <code># dpkg -l | grep -E '^rc' | awk '{print $2}' | xargs dpkg -P</code>
+  - Make sure all packages are up to date and the package manager is up to date, then reboot:
+
+```
+# apt update && apt full-upgrade
+# apt-get autoremove && apt-get autoclean
+# dpkg -C
+# reboot
+```
+
+<!--more-->
+
+  - Take some backups:
+
+```
+# dpkg -l > 2019-12-01-linode18-dpkg.txt
+# tar czf 2019-12-01-linode18-etc.tar.gz /etc
+```
+  - Then check all third-party repositories in /etc/apt to see if everything using "xenial" has packages available for "bionic" and then update the sources:
+  - <code># sed -i 's/xenial/bionic/' /etc/apt/sources.list.d/*.list</code>
+  - Pause the Uptime Robot monitoring for CGSpace
+  - Make sure the update manager is installed and do the upgrade:
+
+```
+# apt install update-manager-core
+# do-release-upgrade
+```
+
+  - After the upgrade finishes, remove Java 11, force the installation of bionic nginx, and reboot the server:
+
+```
+# apt purge openjdk-11-jre-headless
+# apt install 'nginx=1.16.1-1~bionic'
+# reboot
+```
+
+  - After the server comes back up, remove Python virtualenvs that were created with Python 3.5 and re-run certbot to make sure it's working:
+
+```
+# rm -rf /opt/eff.org/certbot/venv/bin/letsencrypt
+# rm -rf /opt/ilri/dspace-statistics-api/venv
+# /opt/certbot-auto
+```
+
+  - Clear Ansible's fact cache and re-run the playbooks to update the system's firewalls, SSH config, etc
