check stuff

see how much space we have

$ df -h

Filesystem	Size	Used	Avail	Use%	Mounted on
tmpfs	1.6G	1.8M	1.6G	1%	/run
/dev/mapper/ubuntu--vg-ubuntu--lv	351G	192G	144G	58%	/
tmpfs	7.8G	0	7.8G	0%	/dev/shm
tmpfs	5.0M	4.0K	5.0M	1%	/run/lock
/dev/sda2	2.0G	370M	1.5G	21%	/boot
/dev/sda1	1.1G	6.1M	1.1G	1%	/boot/efi

extend the logical volume - by half of what's free

$ sudo lvextend -l +50%FREE /dev/mapper/ubuntu--vg-ubuntu--lv

extend the file system

$ sudo resize2fs /dev/mapper/ubuntu--vg-ubuntu--lv

and another run of df should show more free space
