Does not compile under mono-devel 6.12 on Ubuntu 21.04

[ericx]

Not sure where to find error messages for you, but I'm using the latest mono-devel from the official Ubuntu repo:
deb [arch=amd64] https://download.mono-project.com/repo/ubuntu stable-focal main

Keepass startup attempts to compile KPSimpleBackup.plgx, fails, and posts a dialog box saying that it's not compatible and I may need to install mono. For the record: the older dbBackup.plgx works fine, but I haven't tried any other plugins.

Ubuntu: 21.04 (hirsute)
Keepass: 2.47 (64-bit)
mono-devel: 6.12.0.122-0xamarin1+ubuntu2004b1

I honestly have never tried to use the plugin on Ubuntu.

On the KeePass website it states:

Plugins:
On some Linux systems, the mono-complete package may be required for plugins to work properly.
