describe the problem

Hello,

i am new to Arch-Linux (using Manjaro usually) and have a lot of trouble with archinstall and need some Help please, because python exceptions occur.

Case 1:
on my physical PC the setup suddenly interrupted, i dont now why exactly they want to touch nvme0n1p10:

target path already exists
archinstall.log

Case 2:
even in my VM the setup dont complete:

Unable to determine new partition number: {path}
archinstall-vm.log

Does this happen with archinstall v2.8.5 as well? I take it you're using v2.8.1.

[sh3bang]

yes. id did already a "pacman -Sy archinstall" (update to 2.8.5) and the error still occur.

Haven't read thoroughly yet, but initial hint:

it looks like you're re-using partitions.
Because the disk was never wiped - and it's trying to re-create subvolumes specified during manual partitioning.

[sh3bang]

yes, i have also other partitions and Linux distributions installed and want to install Arch only on a specific partitions.

But even on Case 2 (see log file from above), where i installed a fresh VM with "Suggest partition layout" the setup failed

[Torxed]

We should handle those scenarios, so we'll have to debug and fix this obviously.
It was just preliminary debugging information to find the root cause.
The second one is a bit surprising tho, that should work.

it`s easy to reproduce! Download Arch-Linux ISO, create a new KVM, run archinstall, choose "Suggest partition layout" and maybe ext4 as FS and Setup will fail.
