Bug Description
I have two EFI System Partitions (ESPs) on my system: the first is at sda2, and the other is at sda6. When installing Ubuntu MATE (the second of two Ubuntu installations on my system), I specified "do not use the partition" for sda2 in an attempt to prevent the /EFI/ubuntu that's already on sda2 from being overwritten, and also specified sda6 as the location of the ESP where /EFI/ubuntu should be installed. Despite theses steps, the installer installed /EFI/ubuntu to sda2.
WORKAROUND:
I reset the flags for the original ESP on sda2 from "esp" to "msftdata" using gparted, which prevented the installer from installing /EFI/ubuntu to sda2. Because only sda6 had a flag set to "esp" the installer installed to the ESP on sda6, as desired. After installation, I switched the flags for sda2 back to "esp" and all works as expected. (Now I can dual boot between two Ubuntu installations, one being vanilla Ubuntu and the other being Ubuntu MATE.
NOTE:
This bug is relate to, but is NOT the same as, Bug #1855874. Bug #1855874 discusses that a second installation overwrites a first installation at /EFI/ubuntu (which shouldn't happen).
This issue identified in this bug is that, even when specifying "do not use the [first ESP] partition" the installer still installs to the first ESP. That is, the installer ignores the instructions.
