Tried to "upgrade" ubuntu 20.04->22.04, by doing clean install
In partition manager I've killed old / partition (omit that, imagine i wanted dual boot) created new / partition and checked format then i've picked partition which holded old /home selected use ext4 and mount point /home
didnt checked box to format it, to preserve old user data
after reinstall all the data gone - in home there is only new user so basically new installation killed old user home directory, despite it was separate from binaries partition, so old system (if i needed to keep it) wont work well, and i cannot rescue my data!
where are old folders from /home partitions? why its empty, why that happened?
basically i want to setup thing with shared /boot and /home to share userdata and have single bootloader, and have multiple distros(binaries versions) - each one on its own partition.. how to achieve that? what should be my step before adding new Ubuntu version X to PC?
current layour is as follows (know that i need to add /boot):
nvme0n1
│
├─nvme0n1p1
│ vfat FAT32 71EE-5F88 473,1M 7% /boot/efi
├─nvme0n1p2
│ ext4 1.0 48f549cb-ecfb-42fa-8ba9-9f4661f06240 28,4G 18% /
├─nvme0n1p3
│
├─nvme0n1p4
│ ntfs System
│ A2BA28A0BA2872C9
└─nvme0n1p5
ext4 1.0 shome 6d8dc655-4309-4caa-95a7-56cf2a3b7e30 118,4G 0% /home
You most likely thought you didn't click 'format', but you did. There's often a lag between the click and the checkmark appearing in the installer, so this a mistake you need to double-check for after you made your partition layout.
I almost made this mistake once, this is why I am proposing this theory. Double-checking saved my data.
