[Ubuntu 18.04 LTS has reached the end of it's *standard* support life](https://fridge.ubuntu.com/2023/05/13/extended-security-maintenance-for-ubuntu-18-04-bionic-beaver-begins-31-may-2023/) thus is now off-topic here unless your question is specific to helping you move to a supported release of Ubuntu. Ubuntu 18.04 ESM support is available, but not on-topic here, see https://askubuntu.com/help/on-topic See also https://ubuntu.com//blog/18-04-end-of-standard-support

A number of PPAs only provide support for *supported* releases; the PPA you specifically mentions covers all *standard* support LTS releases, which currently is 20.04 & newer. Ubuntu 18.04 LTS is now in ESM support with its *standard* support ended after 5 years.

Support for Ubuntu 18.04 was removed from Ondřej Surý's PPA on June 15, 2023 as that version of Ubuntu is no longer supported. As per the description on the PPA landing page:

... Only Supported Versions of PHP (http://php.net/supported-versions.php) for Supported Ubuntu Releases (https://wiki.ubuntu.com/Releases) are provided. Don't ask for end-of-life PHP versions or Ubuntu release, they won't be provided.

If you really must use PHP 8.1 on an Ubuntu 18.04 server, then your only semi-supported way forward would be to use Docker containers. However, if Docker is no longer making their tools available for 18.04, then you'll need to consider updating from 18.04 to something newer.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
