Using the supported Windows operating system, all of the USB Type-C monitors (P2219HC/P2419HC/P2719HC) can do the MST DP out port daisy chain.
There are two setups a user can use =
* Laptop has its AC power cable connected
* Laptop lid is closed
* PC USB Type-C port --> P2719HC USB Type-C cable (C to C) --> P2719HC USB Type-C in port (Menu- Display- MST On)
* P2719HC DP out port --> P2719HC DP to DP cable --> Second P2719HC DP in port (Menu- Display- MST Off)
-or-
* PC DP out port --> P2719HC DP to DP cable --> P2719HC DP in port (Menu- Display- MST On)
* P2719HC DP out port --> P2719HC DP to DP cable --> Second P2719HC DP in port (Menu- Display- MST Off)

I suppose there are no problems with the latest versions of Ubuntu,
right?

That is something Dell cannot know because we only tested the monitor in Windows. You should post the Ubuntu question on our Linux General Forum.

Since they're both 1080p displays, yes there will be enough bandwidth to daisy chain even when using USB-C to the first display. If they had been QHD displays, it would have depended on whether DisplayPort HBR3 over USB-C was supported by both the system and displays (rather than the more common HBR2) or whether the display supported being configured to use the USB-C link purely for video, which would allow dual QHD even over HBR2 but would have restricted USB speeds to USB 2.0 -- although if you didn't plan to plug any USB 3.0 devices into the display's ports, that wouldn't have been an issue. If you had an HBR2 system and the display didn't offer that mode, you'd have to use a USB-C to DP cable to connect to Display #1 to have enough bandwidth to run dual QHD -- but then of course you lose USB entirely.
However, 27" 1080p generally isn't a great choice. Even a 24" 1080p display has lower pixel density than the 96 ppi that Windows assumes, so 27" just stretches that out across an even larger canvas. The result is that the image will appear noticeably grainy. A 27" 1080p display is a great choice as a kiosk display that is designed to be viewed from a greater distance and where size therefore and low cost matters more than sharpness, and it can also be a good choice for people with poorer eyesight, but otherwise there's a reason that QHD is the much more commonly found resolution for 27" displays.
