Encrypted OS and resize partition during installation Ubuntu

br flag

I have question, I have 120GB ssd and I want to install Ubuntu and encrypt this installation, I also need to resize this encrypted system partition to 40GB and rest leave for something else. I am trying to it when installing Ubuntu but when I will choose encryption then I can’t resize partition or when I choose to resize then I can’t encrypt this partition. Can you tell me please what am I doing wrong.

You can't use the guided installation for this scenario. You will need to choose "something else" during installation and manually partition.

Make the partition changes you want before starting the installer (you didn't mention an OS/release/flavor but there are 2 or 3 tools on each ISO that will do it).; just as Nmath has said.

I have ubuntu-21.04-desktop-amd64. I know that I can choose "something else" during installation and manually partition ssd but this option wont let me encrypt installation. I googled that I could encrypt system after OS is installed but I am not Terminal expert, I rather would like to use something with GUI. Is there any GUI software to encrypt all system ?

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.
