The following signatures were invalid: XXX5650AB - Ubuntu 20.4

Hello,

I’m trying to install the Community Edition on a fresh Ubuntu 20.4 server. I’m using this as a guide: platform-install-packages/install-kaltura-focal.md at Propus-16.6.0 · kaltura/platform-install-packages · GitHub

Things have been going fairly well until I execute ./install_kaltura_all_in_1.sh

I get the following error:

Err:2 Index of /repo/apt/debian propus InRelease
The following signatures were invalid: 8118B7B578D4BA50032E3B740E221B84C95650AB

So frustrating…so I’ve tried:

root@kalt:~# sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 8118B7B578D4BA50032E3B740E221B84C95650AB

gpg: key 0E221B84C95650AB: “Kaltura Inc deb repo community@kaltura.com” not changed
gpg: Total number processed: 1
gpg: unchanged: 1

…the tried to install again…same error.

So, any thoughts on what I should do? I read that this error might be happening because debian is no longer supported??!?! Yet, the documents show Ubuntu 20.4 as being supported.

Any idea on what I might need to do to get past this error?

Thanks
