Ubuntu

no available python error during installation of Ubuntu Server 18.10

Asked by Tomas Hubik

Hello,

I am trying to install Ubuntu Server 18.10 on a brand new Intel NUC7i5BNH with Samsung 850 EVO M.2 SSD.

When the boot proces starts from the USB drive, I saw these warnings/errors:
Timed out waiting for device dev-disk-by\blahblah
Dependency failed for /subiquity_config

Then the process continues, I was able to select keyboard, define partitions, etc, but on step 8, the installation fails with the following error:
no available python? [PY30R2_DEBUG=1 for more info]

I tried to reset BIOS settings to defaults, but no luck.

Does anyone have any idea what is going wrong?

Thank you.

Best regards
Tomas

Did you MD5 test the ISO you downloaded or did you use torrents to download the ISO?

For a server I can suggest 18.04 which is LTS. Ubuntu 18.10 is only supported for 9 months

I have downloaded this iso: http://releases.ubuntu.com/18.10/ubuntu-18.10-live-server-amd64.iso and successfully verified the MD5 and then used Rufus to make a bootable USB drive - I have also successfully verified the sectors on that USB drive.

Also I would like to use regular Ubuntu version, as it will not be a regular server. I am planning to have a home server together with media server from it so I would like to benefit from the newest packages and I do not mind upgrading to new Ubuntu every half year.

Any ideas, what is wrong here? :)

Does 18.04 work or do you get the same error?

18.04 is showing the same errors/warnings during the boot of the install (Timed out waiting for device dev-disk-by\blahblah and Dependency failed for /subiquity_config), but I am able to successfully finish the installation.

Try with http://cdimage.ubuntu.com/ubuntu/releases/cosmic/release/ubuntu-18.10-server-amd64.iso
or http://cdimage.ubuntu.com/ubuntu/releases/bionic/release/ubuntu-18.04.1-server-amd64.iso

What is actually the difference between the two images?

Right now, I have done installation from http://releases.ubuntu.com/18.04/ubuntu-18.04.1-live-server-amd64.iso, then switch to normal from lts and did release upgrade and everything looks like it is working, so I do not want to break it now, but if the live-server is some specific version, I can reinstall.

Thank you.

http://cdimage.ubuntu.com/ubuntu/releases/cosmic/release/ubuntu-18.10-server-amd64.iso also works without problems. So I have reinstalled the system with this one and everything looks fine, thank you for the help.
