How to make a quick shot before upgrade system?

How to make a quick shot before upgrade the system? so I can roll back quickly if met some errors which are so hard to resolve.

Just like the behaviour in VMware.

If using *btrfs* you can rollback changes, eg. refer https://askubuntu.com/questions/1033990/howto-rollback-failed-release-upgrade

The safest way (I am familiar with) to have a backup installation, in case anything breaks, is to use something like Clonezilla to backup your installation.

It is very easy to use, you only need a suitable place for your backed up information.

Or you could try TimeShift. Or BackInTime.

There are quite a few posts out there with variants.

  1. Create bootable backup of my existing ubuntu installation

+1; I use [Clonezilla](https://askubuntu.com/questions/958242/fastest-way-to-copy-hdd/958248#958248) too.

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.
