I can confirm that solution from "Jb (jebsolutions)" is working. Thanks! you saved my day Nothing else worked on ubuntu-server-alternate 18.04 even that preseed partman/unmount_active boolean true preseed partman/confirm boolean true #preseed partman-lvm/confirm boolean true #preseed partman/conf

I was running into the same issue and finally by luck happened upon a set of slides that allowed me to automate this and there was an accompanying code repository with the full preseed file. https://github.com/uweplonus/adia- install/blob/master/initrd/preseed.cfg#L3 Many people suggest using `pre

Just an addendum. The above works for cd (which always forced read only). To also work for usb I had to add the "-oro" to the command: # -- Hack starts! block installer mounting /dev/sda1 on /media # We do this...by mounting the install media (/dev/sd0 or /dev/sd?) onto /media first! # so when

[Bug 1347726] Re: ubuntu14.04 installation hang on "The installer has detected that the following disks have mounted partitions"

This is a really annoying bug. In my opinion there is no good really to mount /dev/sda1, the /boot partition from my previous install... I was able to work around the bug by adding this to the %pre section in the kickstart config: # -- Hack starts! block installer mounting /dev/sda1 on /media #

[Bug 1347726] Re: ubuntu14.04 installation hang on "The installer has detected that the following disks have mounted partitions"

Preseed-based workarounds are insufficient when installing from a USB device onto a bare (unpartitioned) drive, as it's not possible for the preseed to actually load (the installer gets stuck "loading the CD-ROM" since the proper device has already been mounted on /media). mountmedia runs prior to
