Upgrading Ubuntu 16.04 to 18.04

[desisn.com]

I have my Virtualmin setup on a Linode node. Everything works ok, but I would like to eventually upgrade to 18.04. What is the best way to do the upgrade. Is there anything I must be careful with? I read this post here, that said it is possible:

Upgrading Ubuntu 14.04 to 18.04

Hi anyone, I saw the guide for upgrading Ubuntu 14.04 Trusty to 16.04 Xenial at https://www.virtualmin.com/documentation/system/upgrades-and-migrations. There is no guide for upgrading 16.04 to 18.04 or even 14.04 to 18.04. Since I run a Ubuntu 14.04 server I think it is time to upgrade to one of the newer LTS Ubuntu’s. Has anyone experience in this? What would be your advice? Thanks a lot! BTW: Newer PHP versions are of no concern here.

This official update document regarding the update from Ubuntu 12.04 to 14.04 - https://www.virtualmin.com/documentation/system/os/ubuntu-trusty-to-xenial - mentions:

Reset Dependency Flags

These packages are already installed, but the following command will tell apt not include them anytime “apt-get autoremove” is run:

apt-get install bind9 spamassassin spamc procmail libnet-ssleay-perl libpg-perl libdbd-pg-perl libdbd-mysql-perl quota iptables openssl python mailman subversion ruby irb rdoc ri mysql-server mysql-client mysql-common postgresql postgresql-client awstats webalizer dovecot-common dovecot-imapd dovecot-pop3d proftpd webmin usermin webmin-virtual-server libcrypt-ssleay-perl webmin-virtual-server-theme webmin-virtualmin-awstats webmin-virtualmin-htpasswd clamav-base clamav-daemon clamav clamav-data clamav-freshclam clamav-docs clamav-testfiles libapache2-mod-fcgid scponly apache2 apache2-doc libapache2-svn libsasl2-2 libsasl2-modules sasl2-bin procmail-wrapper php-pear php5 php5-cgi webmin-security-updates

Is this step required when upgrading from Ubuntu 16.04 to 18.04 as well? Or should I wait a bit and see when Ubuntu 20.04 is fully stable and supported by Virtualmin?

Thanks for your input.

I believe there is basic support for Ubuntu 20.04LTS in Joe’s install.sh. You could see if that works out well for you. Honestly, I think migrating to a new server is the way to go. Upgraded systems always seemed messy and unpredictable to me. When running newly built systems you are running configurations in their intended state.
