Comment 5 for bug 1755968

I have a possibly related problem.

I have successfully installed ubuntu-18.04.1-desktop-amd64 on an old Asus laptop (K70IO) from a DVD. Everything behaves normally.

But when I try to install ubuntu-18.04.1-desktop-amd64 (replacing rather than updating 16.04) on my HP Pavilion dv7 6080eo laptop, which currently runs Windows in dual boot with Ubuntu 16.04 LTS for amd64, I never get the screen with the Try Ubuntu or Install Ubuntu choice. Instead the GUI drops into "terminal mode" showing some errors, and after some time I can log into "Try Ubuntu" mode.

When I try to install ubuntu-16.04.1-desktop-amd64 on the HP machine, I do not have this problem. I can then chose between Install or Try Ubuntu.

This is true for a DVD I finally succeeded to burn (having struggled with Brasero on 16.04 which hangs in checksum verification, burning on Windows 7 which gave the wrong hash, and finally succeeded with Brasero on 18.04 on my Asus), and I have verified the DVD with two methods:

  1. Compared the MD5 sum of the .iso file using md5sum with the value on the web, f430da8fa59d2f5f4262518e3c177246, and checked the DVD using the command:

    df if=/dev/sr0 | head -c $(wc -c .../ubuntu-18.04.1-desktop-amd64.iso) | md5sum

    which also returned f430da8fa59d2f5f4262518e3c1.

  2. Verified the DVD integrity, booting the HP with ubuntu-18.04.1-desktop-amd64 DVD and used the Check CD for defects menu option, which was successful.

The "terminal output" I get before the "installation" on the HP drops into try mode I have attached. The output contains, among others, the GUdev-CRITICAL lines. I do not know if these errors are causing the behaviour, or if it may be the line "[FAILED] Failed to start the daemon for systemd-networkd.", or something else.
