Support for Drupal 7 is ending on 5 January 2025—it’s time to migrate to Drupal 10! Learn about the many benefits of Drupal 10 and find migration tools in our resource center.During installation via Drush with fresh 8.2.6 core I've got the following error:
The following projects provide some or all of the extensions not found: [ok]

Project mayo (8.x-1.3) downloaded to /var/www/example.com/themes/mayo. [success]

On the reported place - line 43 col 28 - I found percentage sign. Actually there are several parameters like tablet_portrait_page_unit, tablet_portrait_sidebar_unit with percentage sign as a value. When I replaced the sign with values like '80%', '20%' installation was successful.
Probably the yaml parser, which is currrently in use, does not allow single percentage as a value, so something have to be done here?

jhodgdonI think the % signs need to be quoted. I am getting this error running under 8.5.x:
Not quoting the scalar "%" starting with the "%" indicator character is deprecated since Symfony 3.1 and will throw a ParseException in 4.0 on line 77.
Also there is a duplication in the file:
Duplicate key "global_default_layout" detected whilst parsing YAML. Silent handling of duplicate mapping keys in YAML is deprecated since Symfony 3.2 and will throw \Symfony\Component\Yaml\Exception\ParseException in 4.0 on line 94.
Note: Both of those line numbers refer to lines in the Symfony YAML parsing code, not lines in the mayo.settings.yml file.
See also this somewhat related issue...

jhodgdonAlso, the attached is what you get if you use the Configuration module in Core to export the settings -- note that the duplicated key has been omitted, and the '%' are output in quotes. So, probably this should be put into the mayo.settings.yml file. The comments that are in the YAML file currently should instead be put into the schema file instead (see related issue) as descriptions/labels.

Balu Ertl@jhodgdon Thank you for the hint, I stumbled into exactly the same issue, and indeed encapsulating standalone
%characters into single quotes has solved my case as well.In your editor search for this pattern:
(\:\s*)\%(10 occurences were for me), then replace to$1'%'pattern.Comment #6
