When trying to update my system with sudo apt update and sudo apt upgrade, Apache2 is throwing an error and preventing my system from updating:

Setting up apache2 (2.4.52-1ubuntu4.1) ...

It says javascript-common does not exist as Jos pointed out, but when I try to install it per his recommendation, it says otherwise:

$ sudo apt install javascript-common

Below are all the outputs I could think of to include, but I'm sure there's more information to be found. Unfortunately, I'm still pretty new to the terminal interface, and I'm not sure where else to look for troubleshooting info.

$ apache2 -v

Server version: Apache/2.4.52 (Ubuntu)

Server built:   2022-06-14T12:30:21

$ apache2 -t

[Tue Aug 23 07:45:27.890824 2022] [core:warn] [pid 921747] AH00111: Config variable ${APACHE_RUN_DIR} is not defined

apache2: Syntax error on line 80 of /etc/apache2/apache2.conf: DefaultRuntimeDir must be a valid directory, absolute or relative to ServerRoot

I get the same message above when I try to run debug also:

$ apache2 -X

[Tue Aug 23 07:50:00.684706 2022] [core:warn] [pid 922041] AH00111: Config variable ${APACHE_RUN_DIR} is not defined

apache2: Syntax error on line 80 of /etc/apache2/apache2.conf: DefaultRuntimeDir must be a valid directory, absolute or relative to ServerRoot

When I navigate to /etc/apache2/apache2.conf, line 80 says the following: DefaultRuntimeDir ${APACHE_RUN_DIR}

Any help troubleshooting this issue would be greatly appreciated! If it helps, the purpose of apache2 on this system is to host a web server of Bitwarden password manager.
