How to install Ubuntu alongside Mac OS Catalina?

How do I install Ubuntu alongside Mac OS Catalina?

I installed rEFInd and created a bootable Ubuntu 22 v running.

But when I choose Installation Type, I do not get the option to "Install Ubuntu alongside MAC OSX", but only "Install Ubuntu (Will erase data on partition...)"

I created the bootable USB stick with etcher.

Have I missed something? What should I do?

Which model of Mac are you trying to install Ubuntu onto? Is your Mac partition encrypted?

Ubuntu 22? Don't forget 22 & 22.04 are different systems, Ubuntu Core 22 being a *flavor* of Ubuntu 22.04 LTS Server intended for *headless* cloud or IoT use. You don't normally install a *headless* server system in dualboot, it's normally used with desktop systems & whilst Desktop is available for 22.04 & 22.10 - it's not available for 22.

I haven't checked in a while, but the last time I did, Ubuntu didn't offer very flexible options for resizing macOS partitions at install time. Thus, you may need to use macOS utilities to shrink the macOS partition before booting the Ubuntu installer, or provide a blank disk for the Ubuntu installation. Even then, you may need to use the "Something Else" option to manually create partition(s) for Ubuntu.

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.
