Having accepted the invitation to update to 24.04 from 22.04 I have a none usable PC. After some days I have managed to create a 'Ubuntu 24.04 live disc' and boot my pc to it, I think!
My aim is to get access to my home folder on the SSD which has 'LVM'. Using Files I am informed that /home/ has 561 items totalling 11 MB with 8.3 GB free, this is not what I expected for a 500 GB SSD. In GParted it lists /dev/nvme0n1 as 476.94 GiB; /dev/nvme0n1p1 as EFI System Partition fat32 512MiB flagged as boot,esp; /dev/nvme0n1p2 locked lvm2pv 476.44 GiB used flagged as lvm. $ sudo lvscan reports that '/dev/vgubuntu/root' and '/dev/vgubuntu/swap_1' are Active.
Doing 'sudo vgchange -a n vgubuntu' and then 'sudo vgchange -a y vgubuntu' has not changed visibility of my files. 'sudo vgscan' obtained volume group as vgubuntu.
How do I get the files in my /home/ visible and then copy them off on to a USB HDD?
