Iwant to upgrade my 16.04

pk flag

Since my 16.04LTS has expired, in upgrading 16.04 to 20.04 is it better to upgrade one year at a time or all 4 years at once? I've not ever upgraded before so I'm not sure how it works.

Your upgrade path is going to be 16.04 to 18.04. Then from 18.04 to 20.04. See the thread that this question is closed as a duplicate of - https://askubuntu.com/questions/91815/how-to-install-software-or-upgrade-from-an-old-unsupported-release

When your setup, is very personnalzied, it is better to update LTS to LTS to LTS until last one. If your setup is very standard, you can risk an update of all at once. In both case, you should do a cold backup of your /home & / before starting

You cannot upgrade one year at a time, 17.04 was NOT a LTS thus is EOL (it reached EOL early in 2018) and *release-upgrade* tools will **not** upgrade to you an EOL release. LTS or *long-term-support* releases are the first release of an *even* year, ie. 16.04 -> 18.04 -> 20.04.

You didn't provide specific details; is this is a server install? desktop install? You can *upgrade via re-install* which is my fallback; but I'm a desktop users (*where it's terrific; but as it erases system directories it's not as good with server apps as some restore of data maybe required*). It allows me to switch releases; with my *manually installed* Ubuntu repository packages re-installed automatically & user files not touched.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
