[Bug 1901137] [NEW] I tried to install a fresh install of Ubuntu-Mate 20.10 on a machine which has other OSS also in a Multiboot System. After completing the installation it is unable to Install Grub and failed. I tried to install on ?dev/sda , /dev/sdb and also /dev/sdb7 the partition where I have tried to install the Ubuntu Mate-20.10 . The grub failed to install in all the three attempts. The installer fails at the stage when it tries "grub-install".
