I installed ubuntu with custom partition layout.

boot/efi

root (/) as btrfs

home (/home) as btrfs

swap partition

lsblk looks like :

NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS

nvme0n1 259:0 0 953,9G 0 disk├─

nvme0n1p1 259:1 0 1,2G 0 part /boot/efi├─

nvme0n1p2 259:2 0 230,5G 0 part /swap│ /├─

nvme0n1p3 259:3 0 705,8G 0 part /home└─

nvme0n1p4 259:4 0 16,3G 0 part

blkid looks like :

/dev/nvme0n1p3: UUID="c7fad709-d03d-4dad-9061-777e3ce28cb8" UUID_SUB="02ff67a2-776c-43e0-88ea-758fbe5e9e66" BLOCK_SIZE="4096" TYPE="btrfs" PARTUUID="e215ee62-71f1-d842-9899-d3b0c69b8f9d"

PARTUUID="07ca766f-2c54-4c3e-893b-e9795b215637"

Also FSTAB looks like :

UUID=4922-93B0                            /boot/efi      vfat    defaults   0 2
UUID=7e1daa09-4f81-4a7e-88f4-8708f6d242e5 /              btrfs   subvol=/@,defaults,noatime,autodefrag 0 0
UUID=7e1daa09-4f81-4a7e-88f4-8708f6d242e5 /swap          btrfs   subvol=/@swap,subvol=/@swap,defaults 0 0
UUID=c7fad709-d03d-4dad-9061-777e3ce28cb8 /home          btrfs   defaults,noatime,autodefrag 0 0
/swap/swapfile                            swap           swap    defaults   0 0
tmpfs                                     /tmp           tmpfs   defaults,noatime,mode=1777 0 0

At first it doesnt look ok for me. Am I wrong ? Also swap partition is not visible or active

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.
