preseed file fails to configure various settings

[Thomas]

System Ubuntu 18.04.2 LTS

Providing an /preseed/ubuntu.seed file with user configuration fails with following symptoms:

This line

  d-i passwd/user-fullname string SCOE Admin

puts the full name in the "Your name" box, but also the string "SCOE" is then written to the "Pick a username" box.
The following has no effect at all:

  d-i passwd/username string scoe-adm

Also putting the string inside " has no effect:

  d-i passwd/username string "scoe-adm"

Still only "SCOE" is visible in the "Pick a username" box.
Same goes with the password:

  passwd/user-password password 'mypass123'

(Note that this did not work in Ubuntu 14 as well)

------

Setting the timezone not work either.
Specifying the swap partition size in % of the installed memory fails as well. In the below setting only 1GB of swap is assigned although the system has 16GB installed (note that this worked in Ubuntu 14 LTS):

d-i partman-auto/expert_recipe string \
        root :: \
                256 256 256 fat32 \
                        $primary{ } \
                        method{ efi } format{ } . \
                100% 100% 100% linux-swap \
                        $primary{ } \
                        method{ swap } format{ } . \
                102400 102400 102400 ext4 \
                        $primary{ } $bootable{ } \
                        method{ format } format{ } \
                        use_filesystem{ } filesystem{ ext4 } \
                        label{ root } \
                        mountpoint{ / } . \
                409600 409600 -1 ext4 \
                        $primary{ } \
                        method{ format } format{ } \
                        use_filesystem{ } filesystem{ ext4 } \
                        label{ home } \
                        mountpoint{ /home } .

indicator-appmenu package was pre-selected and is probably wrong
