HI,
I just installed KDE lite version on Lenovo Legion 5 with Ryzen 7 processor. I installed in on an existing EXT4 partition. At the last bit of the installation the installer gave an error something about useradd cannot run. I did not get a screenshot but there was an error and the installation stopped.
I installed 201119 and it installed without any problem. However this time I chose to install on existing partition, which the installer then formatted to btrfs. So looks like the newer image solved the issue.
I installed it on another laptop (Intel based with integrated graphics) with EXT4 partition and it did go well initially but could not update using pacman. I had to uninstall Timeshift and the problem went away.
Yeah timeshift fails to create a snapshot on ext4 thats why. Removing the whole thing also removes the hook which creates the snapshot
Make sure to backup properly if you are not using the snapshot feature.
Glad you got this sorted
