Comment 7 for bug 1767799

I had Kubuntu 16.04 previously, and encountered a problem doing fresh install of Xubuntu 18.04. Used USB boot drive created from ISO image; chose to install Xubuntu; chose to manually configure; set existing partitions as previously configured, choosing to format / and /boot. All partitions are XFS except /boot and /boot/efi which are ext2 and vfat, respectively.

I was stuck at the "who are you" setup screen repeatedly getting the "ubi-usersetup failed with exit code 141" error. In the logs, I have the "ecryptfs-setup-swap failed" error. I also have the "'PageGtk' object has no attribute 'error_dialog'" error and the message that "Ecryptfs is deprecated".

So, on the command line I checked to see if ecryptfs-setup-swap was installed, and it wasn't. So I used "sudo apt install ecryptfs-utils" to install it and tried completing the user setup step again. Got a wait cursor for a while, popped back to console to check syslog and it shows what appeared to be some success with mounting swap. Back to GUI and system reported that the installer crashed.

Continuing in syslog, I see it can't create the home directory for my new user, with error "xubuntu user-setup: adduser: Could not find program named `ecryptfs-setup-private` in $PATH". This executable, as well as ecryptfs-setup-swap, are in /usr/bin, owned by root:root with 755 permissions. chpasswd for the new user I was trying to create failed, "Authentication token manipulation error".

In the previous (16.04) setup, I'd chosen to encrypt the home directory for one user, with other users having been created without that option. The home partition is mounted on /target/home and I am able to see the contents of the subdirectories for users not using encryption.

I'm hoping someone can provide a workaround that'll let me proceed. I will attach the install debug and syslog files from the affected system.
