Softaculous or Manual Upgrade

Have just taken over management of a couple of sites running OwnCloud
Both running V 8.2.8 and the web admin telling me to upgrade to 8.2.7

Do I click that "Update" button or go the manual path as outlined here?

I've had issues with Softaculous on other code installs and am not wishing to set myself up for grief if I don't need to.

Version 8.2.7 is the current version. Can you check the version number in:
and open on your browser.

My bad ... the current version is 8.2.2 not as indicated in my OP
