wrote 21.04 build 21 March to USB stick after checking image with gtkhash. Used this LIVE USB to install 21.04 to a second USB stick, sdb. Normal installation until near the end when BOOM Unable to install grub in dev/sdb (as superuser). Executing 'grub-install /dev/sdb' failed. This is a fatal error. Only these 2 USB drives sda and sdb are present, no other drives.
This time I freshly created with gparted a GPT USB and a smaller ext4 partition for root, a larger ext4 partition for /home, and a small EFI partition flagged as esp,boot. Boot loader marked as sdb. No files anywhere. Since freshly formatted with Gparted, no formatting during installation. sda is the LIVE USB stick. Choice was 'other' installation, not a full erase and install. This prevents me from test driving 21.04 as a full install. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1920009 Title: 21.04_full installation to USB: unable to install GRUB; grub-install failed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1920009/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
