I'm facing a similar (if not the same) issue. My laptop has the following hardware:
- 500 GB HDD (TOSHIBA MQ01ACF050 (AV002D)) (/dev/sda) - 32 GB SSD (LITEON LST-32S9G-11 SATA 32GB (ZS2110B)) (/dev/sdb) I'm trying to install Ubuntu 19.04 on it as follow, using disk encryption: /dev/sda: - EFI partition: 128 MB - unencrypted /boot: 1024 MB - encrypted volume hosting root (/) formatted in ext4: 31 GB /dev/sdb: - encrypted volume hosting home partition (/home) formatted in ext4: 500 GB I set up the system like this, but when pressing "Install Now", I see the following error pop-up: "The attempt to mount a file system with type ext4 in Encrypted volume (sdb3_crypt) at / failed" I click on "Continue" nevertheless, but the installer is then stuck at "Creating ext4 file system for /home in partition #1 of Encrypted volume (sda1_crypt)...". I've attached the logs (/var/log/*) from the live session. The /var/log/partman file might be of interest. $ dpkg -l | grep ubiquity ii ubiquity 19.04.9 amd64 Ubuntu live CD installer ii ubiquity-casper 1.405 all Configuration hooks for live installer ii ubiquity-frontend-gtk 19.04.9 amd64 GTK+ frontend for Ubiquity live installer ii ubiquity-slideshow-ubuntu 146 all Ubiquity slideshow for Ubuntu ii ubiquity-ubuntu-artwork 19.04.9 all Ubuntu artwork for Ubiquity live installer ** Attachment added: "varlogs.tar.xz" https://bugs.launchpad.net/ubuntu/+source/partman-crypto/+bug/1523194/+attachment/5256476/+files/varlogs.tar.xz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1523194 Title: Can't install /home into separate LUKS encrypted volume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/partman-crypto/+bug/1523194/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
