(sorry, I didn't know I wasn't supposed to cross post immediately)

Hey, I am not sure if this is the place to ask for help, so tell me if it's not (and maybe where to ask).

I am trying to update to the latest Grav release 1.7.29 from (originally 1.6.24, while troubleshooting today updated to) 1.6.31 (using direct-install.

I tried updating with self-upgrade and direct-install <latestVersionURL>.
But, while trying to install, it gives me the following error:

Installing upgrade... [30-Jan-2022 17:04:37 Europe/Cityxy] PHP Fatal error: Uncaught Error: Call to undefined method Grav\Common\Utils::basename() in /var/www/virtual/name/html/tmp/Grav-61f6b713f0bb9/zip/grav-update/system/src/Grav/Installer/VersionUpdate.php:29

From my understanding the files between versions have been changed, and looking at the Grav documentation, the called method basenames() is now in Grav/Common/URI, not in Grav/Common/Utils.

So I assume I located the problem, but have no idea on how to fix it. Since I am not very well versed on this whole topic of managing websites (never set up the site, only maintaining it), I would really appreciate a safe answer on how to update Grav to the newest version which doesn't risk me destroying the functioning of the website.
Thank you for helping! :)

Tried with:
PHP: 7.3 & 7.4
Grav: 1.6.24 & 1.6.31
Admin: 1.9.10
Host: Uberspace
via SSH

@eurokrl Thanks for reporting this -- I didn't remember that we had improved the installation process in 1.7 not to have this issue.

Thanks for the quick reponse @mahagr :)

still having (almost) the same issue, this time it's not the Grav-61f6b713f0bb9 folder, but Grav-61f81d0d41083.
Tried again w/ same PHP versions, old & fresh install of Grav 1.6.31 and selfupgrade & direct-install <LatestVersionURL>.
