WD Mycloud - Loading UBUNTU on device

How do i install UBUNTU server on MYCLOUD since support for my device has ended. I would like to flash this OS on the device. Thanks in advance

Very few operating systems beyond the WD OS have been successfully modified to run on My Cloud devices. See the following discussion for alternate operating systems and the mixed results people have achieved.

Clean OS (Debian), OpenMediaVault and other “firmwares”
