I did some initial troubleshooting and following are my observations. The installed system does not have `cryptsetup-initramfs` package installed. And, initrd does not include `cryptsetup`. Manually installing `cryptsetup-initramfs` onto installed system makes it bootable again.
The issue is also resolved if we install `dracut` instead of `cryptsetup-initramfs`. Looking at the seed files, it was noticed that we cannot include `dracut` or `cryptsetup` in 'core' seed file because of conflict with `initramfs-tools`. However, including `cryptsetup-initramfs` works. Using ISO created with this configuration, the encrypted installation finishes OK and boots OK. The conflict occurs because `ubuntu-mate-core` meta package 'Recommends' initramfs-tools. Looking at Ubuntu and other flavors' meta packages, it seems Ubuntu MATE is the only flavor still recommending 'initramfs- tools' in its core meta package. So we have two options: 1) add `cryptsetup-initramfs` to core seed. Confirmed works with local build. 2) remove `initramfs-tools` from 'Recommends' list of 'ubuntu-mate-meta'. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2161419 Title: UbuntuMATE 26.10 installation using daily build ISO, with encryption enabled, completes but fails to boot thereafter.
