Install Fail: Missing Component: libdrm Ub 20.04

[pac421]

I got the same problem on my side. I tried to reinstall manually the libdrm-dev package but installation always output :

Unsatisfied dependencies. Missing component: libdrm.

I was moving from the non-official displaylink-debian driver to the official displaylink 5.3 driver after receiving the release mail so I also tried to reinstall the non-official displaylink-debian driver and got the same error.
