@OneEagle I did the same too (based on your kind guidance). I have two sites running on php.8.1 and running well (apart from minor issues that every now and then post them here!). However, I would like to make the following observations in this context (i.e., compatibility of php8.1.8 with the requirements) which I don't know if they really matter or not (I am still learning the robes 😀). I will post the summary first and details at the bottom for in depth review by the experts/masters.

1.compared to the list of requirements listed in this link ( https://github.com/unaio/una/wiki/Requirements ) (all for php7.4) the following are missing in the php8.1.8:

-openssl, exif, json, fileinfo

2.When I tried to install them I couldn't install any of them, responses are given below. Some of them there is a message indicate, there is possibly a newer version (? not sure about that), but for json (it was a different message).

3.My question is do we need to do something different to address those "missing" components (especially json) or not.

I appreciate all the help.
