From plasma 5.10.2 to plasma 5.12.3

[smoreau]

On two different machines I wanted to use the backport servers to update plasma from 5.10.2 to 5.12.3. in each case the download was OK. But at reboot I cant go further than the following screen.
See the attached file.
Any suggestions ?
Thanks

Confirmed, do not update Maui 17.06 using xenial backport and neon backport.
The only sequence which worked was
5.10.2 to 5.11.3 to 5.12.1 then 5.12.2 and 5.12.3.

sudo apt-get install -f resolved the problem after the installation.
