HESTIA CP.
but hestia actually isntalls it correctly. that is to say, i can't get it to install any other way (using Composer, being ]my "any other way", boy be lazy!

but. i did do the 1.8 fresh install. i forget why it didn't work. i think it was the same error. about symfony/http-client ... can't resovle it.

Start by reproducing the failed Grav Admin update or fresh install through HESTIA CP on the reported Ubuntu and PHP versions, then inspect the Symfony HttpClient dependency resolution error. Done means the plugin installs or updates to v1.8.0-beta.28 without the reported dependency failure.
