Ubuntu error: the installer needs to remove operating system files
June 18th 2009
I started installing Ubuntu Netbook Remix 9.04 in my ASUS Eee PC, and after the partitioning step, I stumbled upon the following error:
The installer needs to remove operating system files from the install target, but was unable to do so. The install cannot continue
I was installing Ubuntu on top of a previous eeebuntu install, smashing the / partition, while reusing the /home. After minimal googling, I found this bug report at Launchpad, with the same problem (and one year old).
As it turns out, the problem was not with the root partition, as I assumed from the error message, but with the home one. Apparently, Ubuntu didn’t like the idea that my home partition was JFS (maybe it couldn’t mount it, because jfs_utils are not loaded by default). The solution: install the OS ignoring (not using) the home partition, and mount it afterwards.
Shame on you, Ubuntu, this solution is lame!

I solved it by selecting format partition option

Yes, Gary, that would be a solution. However, it cannot apply when one is trying to reuse the JFS partition. Wiping the /home partition was not an option, as I was trying to keep it from a previous install.
The proper solution would be to have the installer ask if you want to install jfs_utils before trying to mount a partition it identified as “JFS”. This seems a catch-22, because installing software can not be done until partitions are finished. However, Ubuntu could accept your choice of reformatting /, reusing /home as JFS, and installing jfs_utils (later). Then, it could first format and mount /, then install the bare minimum, then mount /home, then go on with the installation.
Or the installer could simply support JFS as it does ext2/3/4.
