As the language and setting for directory structure on her machine is NOT ENGLISH; that pages tutorial stalls already at start “cannot move : directory does not exist” and specifically in Finnish in this case “ei voi siirtää kohteeseen : tiedostoa tai hakemistoa ei ole”
This is because sudo mv /etc/apt/preferences.d/nosnap.pref ~/Documents/nosnap.backup
should be sudo mv /etc/apt/preferences.d/nosnap.pref ~/Asiakirjat/nosnap.backup
Many do not realize to change the Documents part according to ones language and installing of snap support for a leaves at that. Could there be a way to translate that docs page? And after that; a simple button to change the language. Seems quite crucial.
Or am i missing something on the page related to this dilemma? Thanks.
Scroll to the very bottom of the page, there is a link that lets you report issues with the page (like on every Ubuntu page), you should use this to report the issue to the web team…
A quick content change that would help might also be to simply back up the config file to ~/ which is not translated at all and will not expose such problems, perhaps you can suggest that in your report …
