We are running Ubuntu Server 18.04.5. I just upgraded from PHP 7.2 to 7.4 because Wordpress was complaining. I followed instructions from here and everything went smoothly. I would now like to remove 7.2, but when I run the command sudo apt purge '^php7.2*' not only does the regex pick up on 7.4 as well as 7.2, it wants to install PHP8. I have pasted the output below. I cancelled before anything actually happened. What am I doing wrong?

The following packages were automatically installed and are no longer required:
dbconfig-common dbconfig-mysql fonts-droid-fallback fonts-noto-mono ghostscript
gsfonts imagemagick-6-common javascript-common libcupsfilters1 libcupsimage2
libfftw3-double3 libgs9 libgs9-common libijs-0.35 libjbig2dec0 libjs-jquery
libjs-sphinxdoc libjs-underscore liblcms2-2 liblqr-1-0 libmagickcore-6.q16-3
libmagickwand-6.q16-3 libpaper-utils libpaper1 php-bz2 php-phpseclib php-tcpdf
php8.0-bz2 poppler-data ttf-dejavu-core
Use 'sudo apt autoremove' to remove them.

The following additional packages will be installed:
libapache2-mod-php libapache2-mod-php8.0 libpcre16-3 libpcre3 libpcre3-dev
libpcre32-3 libpcrecpp0v5 php php-bz2 php-curl php-gd php-intl php-mbstring

  • Ok, so I see my command to remove should have just been simply sudo apt purge php7.2*. Now it doesn't pick up 7.4 also, but it still insists on installing php8.0 – john8791 Jul 14 '21 at 21:33
  • libapache2-mod-php probably depends on some unspecified version of PHP, and apt is trying to pick the highest version that satisfies the dependency – muru Jul 20 '21 at 04:13
  • Thanks @muru. Not sure what the real cause is but I will post what I ended up doing. – john8791 Jul 21 '21 at 16:55

How I ended up "solving" this was allowing the PHP8 install which satisfied APT. Since Apache allows you to select which version of PHP to use with the a2enmod command, executing sudo a2enmod php7.4 keeps Wordpress on 7.4. There hasn't seemed to be any problems. `
