Some of your sources lists are corrupt. Please add text output of `cat /etc/apt/sources.list.d/nodesource.list` to the question by editing it.

To fix it use `sudo sed -i "s/main/focal main/g" /etc/apt/sources.list.d/nodesource.list` and then run `sudo apt-get update` again. If you have errors, please show them.

First of all I should inform you about the prebuilt binary qjackctl-0.9.6 package in the Rui Nuno Capela's Applications PPA, it is installable by:

sudo add-apt-repository ppa:rncbc/apps-focal
sudo apt-get update
sudo apt-get install qjackctl

and then simply start using it.


Or if you are sure about the compilation path, you have to use the following steps to compile from source:

  1. Enable Source Code (deb-src) repositories using Software & Update (software-properties-gtk)

  2. Get fresh packages lists and build-dependencies

    sudo apt-get update
    sudo apt-get build-dep qjackctl
    
  3. Get and compile the source

    sudo apt-get install cmake debhelper-compat qttools5-dev
    cd ~/Downloads
    wget -c https://download.sourceforge.net/qjackctl/qjackctl-0.9.6.tar.gz
    tar -xf qjackctl-0.9.6.tar.gz
    cd qjackctl-0.9.6
    wget http://archive.ubuntu.com/ubuntu/pool/universe/q/qjackctl/qjackctl_0.9.6-1.debian.tar.xz
    tar -xf qjackctl_0.9.6-1.debian.tar.xz
    rm qjackctl_0.9.6-1.debian.tar.xz
    mv ../qjackctl-0.9.6.tar.gz ../../qjackctl_0.9.6.orig.tar.gz
    dpkg-buildpackage -uc -us
    sudo apt-get install ../qjackctl_0.9.6-1_amd64.deb
    
  4. Use compiled application.

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.
