[Bug] Unable to switch from yarn 2 to yarn 1

I've uninstalled yarn 2 via sudo npm uninstall -g yarn. Running yarn -v returns bash: /usr/bin/yarn: No such file or directory.

So far, so good. Then I ran sudo npm install -g 'yarn@1.22.5':

$ sudo npm install -g 'yarn@1.22.5'
/usr/bin/yarnpkg -> /usr/lib/node_modules/yarn/bin/yarn.js
/usr/bin/yarn -> /usr/lib/node_modules/yarn/bin/yarn.js
+ yarn@1.22.5

but whenever I run yarn -v it gives me 2.4.1.

What am I doing wrong?
