Ubuntu Server 20.04 showing wrong storage size

When I am using df -h --total, it shows 131 GB as total even though the hard drive is 256 GB big. Did I make a mistake while setting up the server and can I increase this size?

lsblk output:

Please, [edit] your question and add `lsblk` output together with `df -h` output.

I am completely new to Linux what is lsblk? And now that I do see the storage how can I assign (partition?) it to ubuntu so it is usable?

You should `lvextend` your "root" logical volume. See for example this: https://askubuntu.com/questions/1209796/make-lvm-volume-take-up-entire-disk

I have also noticed, that the installer of Ubuntu Live Server grabs half of the available drive space. It leaves drive space if you want to use [snapshots](https://tutonics.com/2012/12/lvm-guide-part-2-snapshots.html), but you can easily increase the drive space used for the root file system as described in the comment by @FedonKadifeli.

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.
