[Linux Mint] Ugrading gramps from v5,2,4 to v6.0.5, and it is not going well

[DaveSch]

The place_format.xml file was not imported to your 6.0 user directory from your 5.2 folder.

Problem getting started with Gramps 6.0

The code is trying to access a place format that doesn’t exist. Your gramps.ini file was probably upgraded automatically but you didn’t copy over your place_formats.xml file. I suggest that you edit your gramps.ini file and set the “preferences.place-format” entry to 0.
