Preface: I know how to install PHP and do minor troubleshooting.
I run our intranet site on Lubuntu 20.04 (just upgraded) with WordPress 5.5.2 and PHP 7.4.11. I’ve never had an issue with any plugins. We’re looking to improve the search so I purchased searchwp. It would not index. In troubleshooting the issue with the developer he realized that multibyte string extension/functions were not installed.
When I try to install (php7.4-mbstring) it returns:
Some packages could not be installed. This means that you have requested an impossible situation or if you are using an unstable distribution that some required packages have not yet been v=created or moved out of incoming. The following information may help to resolve the situation:
The following packages have unmet dependencies: php7.4-mbstring : Depends: php7.4-common (-7.4.3-4ubuntu2.4) but 7.4.11-1+ubuntu18.04.1+deb.sury.org+1 is to be installedE: unable to correct problems, you have ha;d broken packages.
Can someone tell me what I need to do?
