UPDATE 2018-jul 15 @ 15:20: 1st time installation steps: 18.04 install - normal installation - download updates while installing ubuntu - partition ext4 /boot 4096Mb /format - partition efi 4096Mb - partition swap 32768Mb - partition ext4 / 51199Mb /format - partition ext4 /home 20479Mb /format - write changes to disk? >> continue - where are you >> <user_location> - Who are you ? >> <user_name> - during user info >> Installer Crashed ------------------ 2nd installation steps, here I changed the order of the swap-partition and root-partition: - normal installation - download updates while installing ubuntu - partition ext4 /boot 4096Mb /format - partition efi 4096Mb - partition ext4 / 51199Mb /format - partition swap 32768Mb - partition ext4 /home 20479Mb /format - write changes to disk? >> continue - where are you >> <user_location> - Who are you ? >> <user_name> - during user info >> Installer Crashed ------------------ 3rd attempt: - in start-up menu I choose the option "check disk for errors". At the end of this process 1 file was mentioned as "corrupt" ( I don't know which one ). On my 2nd PC downloaded the 18.04 installer ISO. Re-created a start-up disk on my 2Gb USD-drive. I also tested the USB-drive (got the QMEU box), so it looked OKAY. Rebooted my AMD Ryzen system with the newly created USB-drive. I repeated the 2nd installation steps. Ate the point "Who are you", I choose very simple short user-name and computer-name. And after this the installation worked like a charm :)
So maybe solution to the problem:??? - new USB-drive installation - very simple user-information My AMD-Ryzen is now up and running :) Thanks!!! ** Changed in: ubiquity (Ubuntu) Status: New => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1781788 Title: clean 18.04 install, crash after re-create partition To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1781788/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
