Partition disk when installing ubuntu using LVM

I am trying to partition my disk when installing my ubuntu image: What am trying to achieve is:

Set up 3 main partitions / , /var and /home
encrypt all 3 paritions using LVM encryption module presented by ubuntu installer.

So far i could create the 3 partitions from one part, but i can't place all 3 under the same encrypted partition. What i tried could be seen in the picture 1 below, which leads to an error if trying to install. When i use juste 1 LVM partition and inside 1 partition, the root /, everything works fine, the problem occurs when i create a new partition table under LVM.

I also tried to create 3 LVM partitions, one for each, but it also lead to an error when booting the ubuntu. (picture 2)

Any idea how to proceed in order to create those 3 partitions under LVM encryption? could it be done during the installation of ubuntu? or afterward? or maybe before by editing the iso?

thx for any lead you can share.

(Using virtual box and ubuntu 20.04.1)

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.
