[horde] Issues installing Horde Groupware on new Rocky Linux 8 VPS

[Louis-Philippe Allard]

Hello Maillist!

So I am trying to install Horde Groupware on a brand new VPS based on  
Rocky Linux 8 (replacement of Centos 8 which is unfortunately going  
out of existence in less than 2 months)...

I have followed the instructions of  
"https://www.horde.org/apps/groupware/docs/INSTALL#id3" which have  
worked out very well until I ran the command :

"pear install -a horde/groupware"

which resulted in the following errors:

and restarted from scratch with a VM backup (thanks to Proxmox).  What  
can I do from there?  I googled this for over 2 hours without  
successfully finding a solution or something that remotely looked  
clean enough to do....  Any more data or input on current VPS, please  
ask!  Thanks!
