ubuntu 22.04 lnav from snap unable to write formats directory

[pjgoodall]

I uninstalled a deb package version of lnav: aptitude remote lnav --purge, to replace it with the lnav 0.10.1 version from snap. sudo snap install lnav.

If I ran snap from the command line I got a long list of file access errors:

error:unable to write default config file: /home/<me>/.config/lnav/configs/default/root-config.json.sample -- Permission denied
error:unable to write default config file: /home/<me>/.config/lnav/configs/default/de-keymap.json.sample -- Permission denied
error:unable to write default config file: /home/<me>/.config/lnav/configs/default/default-keymap.json.sample -- Permission denied
error:unable to write default config file: /home/<me>/.config/lnav/configs/default/fr-keymap.json.sample -- Permission denied
error:unable to write default config file: /home/<me>/.config/lnav/configs/default/uk-keymap.json.sample -- Permission denied
[...]

I assumed the config files were left from the deb package with the wrong permissions. So I deleted the $HOME/.config/lnav/ directory, and then: sudo snap remove lnav --purge and then reinstalled the snap.

I tried again, . This time the files were missing.

lnav

From the manual, I tried:

lnav -i extra

I may be doing something wrong, I thought I cleaned up ok.
It looks like the config directories in my HOME directory aren't being set up properly.
