Done! I subscribed the bug reports.
Hello @smurf,
Thank you for submitting your report. 
Could I please ask that you post the link to the bug report here?
Thanks again.
Hello @tkn,
Don't know how connected you are with the Ubuntu installer team.
Just wondering why the move from what I perceive as a Desktop-User-oriented installer (i.e. Ubuntu Desktop Installer) to a Multi-User Network-server Admin-managed installer for provisioning of network-attached desktops (the "Ubuntu desktop provisioning" in what can only be considered to be the Corporate world) which seems contrary to the idea of facilitating the adoption of Linux/Ubuntu by the general masses currently running crappy W?????? and looking for something better, but easy to migrate to !!!
If it is not too misplaced to ask: What Gives ???
Absolutely not connected to Ubuntu or MATE at all.
I'm just a regular Ubuntu-MATE user, nothing more.
regarding the flutter and snap based installer ( 
), i agree
Thank you, @smurf. The community, who've experienced that, can "pile on" with support for that report.
I got some news.
Reading the net I found the solution (for me) I booted from USb key, I entered the safe graphic mode, I switched off BlueTooth and WiFi and the installee worked till the end.
WOW, Luca, that is quite a valuable discovery.
You might want to add that to your bugreport because it might speedup the time for bugtracking by a factor 10 
Yes, tkn, I've already done it.
When I wrote here, immediately I wrote the same there.
