It would be good if there is a message declaring what file system location is not writable causing the failure.
My mounts are as follows: mount | grep /boot /dev/md50 on /boot type ext4 (rw,relatime,stripe=4,data=ordered) /dev/sda1 on /boot/efi type hfsplus (rw,relatime,umask=77,uid=0,gid=0,nls=utf8) that /boot/efi ends up mounted ro is typically because of these two reasons: A. Package: grub-common Version: 2.02~beta2-36ubuntu3 - has a bug that causes the Linux Installer to fail, it requires the file /boot/efi/EFI/ubuntu/mach_kernel to exist which can be fixed by: touch /boot/efi/EFI/ubuntu/mach_kernel B. Some crash causing the /boot/efi needing a fsck, but fsck.hfsplus is not installed. Because of the Apple firmware on MacBooks, the efi system partition must be in the non-standard hfsplus format or the system does not boot. Remount as rw can be fixed by: umount /boot/efi apt-get install hfsprogs fsck.hfsplus /dev/sda1 # sda1 from the mount line above mount -o relatime,umask=77,uid=0,gid=0,nls=utf8 /dev/sda1 /boot/efi # parameters from the mount line above I believe this bug #1573160 occurred in that moment, after the installer had failed, while installing packages, but before I had ensured /boot/efi to be rw.
