I have a fairly new Dell XPS 16 currently running Xubuntu. I am trying to install Endeavour OS on a separate logical volume in order to see if I can get the webcam and sound running smoothly (this is a bit of a hassle on Xubuntu where the webcam currently does not function).
lspci > log.txt && lsusb >> log.txt && journalctl -b -0 >> log.txt && cat log.txt | eos-sendlog
Gives me this output: https://0x0.st/Xxoj.txt
And the install log from:
cat ~/endeavour-install.log | eos-sendlog
Can be found here: https://0x0.st/XxoW.txt
As can be seen in the install log this seems to be what is causing the failure to install (when the progress meter is about 70% done):
Target cmd: QList("umount", "-lv", "/tmp/calamares-root-445teyzf") Exit code: 32 output:
umount: /tmp/calamares-root-445teyzf: not mounted.
Which then gives me the “Could not unmount target system.” error. Some not 100% normal things for the install so far is that I am installing with no bootloader (figured I’d add the entry via Xubuntu to start out). Other than that there is nothing particularly special about the install, it is being put on a spearate ext4 lvm logial volume. I’ve tried switching between xfce and i3wm variants (shouldn’t matter I believe). After the install crashes I’ve tried mounting the volume, but it seems nothing has been written to it. Any ideas on how I could work around this issue would be much appreciated!
welcome here at the purple side 
Only had a short look on the logs, and i see it says “no HotFixes for this ISO” but it should get some … plus it says no bootloader selected?

how exactly you added the LVM to be used a sinstall target? and waht exactly wa scosen on installer to be used ?

Many thanks! This put me on the right track. I must have messed up the lvm setup. When I threw it away, and just made a simple ext4 partition in its place, everything installed fine. There are some graphics issues, but I could sort those out with some googling and adding the appropriate kernel parameters to the grub config for endeavour os. Adding i915.enable_psr=0 sorted out the problem (in case someone runs into graphics glitches on a Dell XPS 16). Now I can experiment to see if I can get the webcam and audio working properly!
feel free to ask me about in case of problems… i had some experience with webcams.
And here https://wiki.archlinux.org/title/Dell_XPS_16_(9640) webcam is listed as working…

if it is the same device on yours…
You could show system specs:
