I cannot update php to version 7.4
I tried to follow the instructions noted in this forum as highlighted in the answer to this question: https://www.linode.com/community/questions/20926/how-do-i-upgrade-my-php-version
However, I tried doing so over weblish. I can't perform the first step because I encounter this error: https://ibb.co/6X6H3V7
I'm not sure how to proceed with updating php at this rate, and I'm seeing my wp-admin site slow down (likely because I didn't update php yet).
If there's anything you need to help diagnose and solve the problem, let me know. Thank you!

Hi @Naphtap! Taking a look at the screenshot you shared, I see the following error message:
E: Sub-process /usr/bin/dpkg returned an error code (1) linode
The following link may help you resolve this issue so you can continue upgrading PHP.

Hello @rdaniels,
I got to step 3 in the link you provided since the first two steps didn't work. I first uninstalled the packages listed under "errors were encountered processing". Then, when I tried to install libpcre2-8-0, I returned the following error on the image below.
Furthermore, my website doesn't work anymore…
Please help; I have to update my blog tomorrow.
Hi @rdaniels,
I just fixed the problem. I had to point dpkg to Debian's repository list instead of Ubuntu's. I used the solution provided here to do so:
https://unix.stackexchange.com/questions/669004/zst-compression-not-supported-by-apt-dpkg
I then followed your solution and successfully updated php to 7.4.
Thanks for your help!
