Public bug reported: When you try to install Ubuntu on the same Windows disk, Ubiquity is stopped on the Updates and other Software screen. So far the solution is to open the GNOME Disks application, and unmount and mount the Windows boot partition several times. When rebooting the installer displays a message that partitions are mounted and if you want Ubiquity to unmount them. When answering Yes, the installation continues.
This does not happen with other distributions, For example KDE NEON (Calamares Installer) or Fedora (Anaconda installer) This happens whenever there is a dedicated Windows partition on the main disk, even if one tries to install Ubuntu on an external disk where there is no other distribution. This is how the partitions of my disks are distributed at the time of the report Disk /dev/sda: 465.8 GiB, 500103634432 bytes, 976764911 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x6fdda5e8 Device Boot Start End Sectors Size Id Type /dev/sda1 * 2048 521261554 521259507 248.6G 7 HPFS/NTFS/exFAT /dev/sda2 521263104 522239999 976896 477M 27 Hidden NTFS WinRE /dev/sda3 522242048 974716657 452474610 215.8G 83 Linux /dev/sda4 974716928 976762879 2045952 999M 82 Linux swap / Solaris ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: ubiquity 18.04.11 ProcVersionSignature: Ubuntu 4.15.0-20.21-generic 4.15.17 Uname: Linux 4.15.0-20-generic x86_64 ApportVersion: 2.20.9-0ubuntu7 Architecture: amd64 CasperVersion: 1.393 CurrentDesktop: ubuntu:GNOME Date: Wed Apr 25 20:34:18 2018 InstallCmdLine: initrd=/ubninit file=/cdrom/preseed/ubuntu.seed boot=casper quiet splash --- BOOT_IMAGE=/ubnkern LiveMediaBuild: Ubuntu 18.04 LTS "Bionic Beaver" - Release amd64 (20180425) ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=C.UTF-8 SHELL=/bin/bash SourcePackage: ubiquity UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: ubiquity (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug bionic ubiquity-18.04.11 ubuntu ** Summary changed: - The installer stops at the Update and Othersoftware screen when Windows is installed + The installer stop at the Update and Othersoftware screen when Windows is installed ** Summary changed: - The installer stop at the Update and Othersoftware screen when Windows is installed + The installer stop at the Update and Other software screen when Windows is installed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1766978 Title: The installer stop at the Update and Other software screen when Windows is installed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1766978/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
