Hi, I've tried to install the 16/4 daily build with Ubiquity 21.04.15, but I'm still experiencing the same problems.
I've just in case filed this bug report: bug #1924823 I've tried to manually install Ubuntu on one of the Ext4 primary partition. Didn't try any other modality, just seen that selecting the "install on the entire disk" option a popup window tells that an ESR partition will be created. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1893964 Title: Installation of Ubuntu Groovy with manual partitioning without an EFI System Partition fails on 'grub-install /dev/sda' even on non-UEFI systems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1893964/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
