After having issues installing Ubuntu on a computer i believe that i have created several partitions rather than simply one Ubuntu OS. What I need is for there to be only one instance of Ubuntu on this computer with all of the available memory.
The output of sudo lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL
NAME FSTYPE SIZE MOUNTPOINT LABEL
├─sda1 vfat 512M /boot/efi
├─sda2 ext4 461,5G /
└─sda3 swap 3,8G [SWAP]
I am hoping there is a way to simply merge the partitions without losing anything, but at worst I could try reinstalling Ubuntu again if needed, though some advice on how to not do this again would probably be needed.
Thanks in advance
