OK, I got rid of the partman bug by rechecking GPT partitions for errors, here is what I found:
If you start the installation from a live USB image - I dd'ed mine, but the USB writer does the same and produces a bad GPT table - and this seems to crash partman after manual partition selection. second bug I encountered is within keyboard setup, as seen below: Exception caught in process_line: Traceback (most recent call last): File "/usr/lib/ubiquity/plugins/ubi-console-setup.py", line 348, in set_keyboard ly = keyboard_names.layout_id(lang, misc.utf8(layout)) File "/usr/lib/ubiquity/ubiquity/keyboard_names.py", line 142, in layout_id return kn.layout_id(lang, value) File "/usr/lib/ubiquity/ubiquity/keyboard_names.py", line 90, in layout_id return self._layout_by_human[value] KeyError: 'Polish' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib/ubiquity/ubiquity/filteredcommand.py", line 145, in process_line return self.dbfilter.process_line() File "/usr/lib/ubiquity/ubiquity/debconffilter.py", line 287, in process_line if not input_widgets[0].run(priority, question): File "/usr/lib/ubiquity/plugins/ubi-console-setup.py", line 502, in run self.ui.set_keyboard(misc.utf8(self.db.get(question))) File "/usr/lib/ubiquity/ubiquity/plugin.py", line 48, in wrapper return target(self, *args, **kwargs) File "/usr/lib/ubiquity/plugins/ubi-console-setup.py", line 350, in set_keyboard ly = keyboard_names.layout_id('C', misc.utf8(layout)) File "/usr/lib/ubiquity/ubiquity/keyboard_names.py", line 142, in layout_id return kn.layout_id(lang, value) File "/usr/lib/ubiquity/ubiquity/keyboard_names.py", line 90, in layout_id return self._layout_by_human[value] KeyError: 'Polish' Setting "Polish" was automatically selected based on my IP location (I guess, since it was auto-selected), and this keyboard/location auto- setting is another problem. I'm not a dev and my python is ~rusty at least, but I share my findings here.
