languagekey - unsupported runtime versions of Ruby, PHP, OTP, etc
- deprecated features or runtime aliases

When I used ruby 1.9.3 to install travis, it will result an error：
```
ERROR: Error installing travis:
ffi requires Ruby version < 2.7.dev, >= 2.2.
```
But when I changed the version of ruby to 2.6.1, it will result another error:
```
ERROR: While executing gem ... (OptionParser::InvalidOption)
invalid option: --no-rdoc
```
I'm confused how to install travis properly.
Then I googled the error message, and found that changing the option to `--no-document` can resolve this problem.
Please correct the documentation to avoid the need for root access:
gem install travis --user-install --no-rdoc --no-ri
Mainly travis linter remained unmaintained for years and reports lots of false errors:
Warnings for .travis.yml:
[x] unexpected key conditions, dropping
[x] unexpected key jobs, dropping
[x] value for addons section is empty, dropping
[x] in addons section: unexpected key apt, dropping
The online form linked to is missing or the link is broken. So, there currently is no way to lint a .travis.yml online? Is this correct?
