Getting a failed to fetch when running apt-get update with bintray

Err:9 https://dl.bintray.com/sbt/debian  InRelease     
 403  Forbidden [IP: 35.155.141.94 443]

E: Failed to fetch https://dl.bintray.com/sbt/debian/InRelease  403  Forbidden [IP: 35.155.141.94 443]   
E: The repository 'https://dl.bintray.com/sbt/debian  InRelease' is no longer signed.    
N: Updating from such a repository can't be done securely, and is therefore disabled by default.

That's mean the repo is not publicly accessible [2].

What should you do:

1. Remove the old Repo

   sudo add-apt-repository --remove "deb http://dl.bintray.com/sbt/debian /"   
   sudo rm -fv /etc/apt/sources.list.d/sbt.list
   sudo rm -fv /etc/apt/sources.list.d/sbt.list.save
   sudo apt update
   

   Based on your sources list. simply remove .list files.

2. Install sbt package from new Repo [3]

   sudo apt install apt-transport-https curl gnupg -yqq
   echo "deb https://repo.scala-sbt.org/scalasbt/debian all main" | sudo tee /etc/apt/sources.list.d/sbt.list
   echo "deb https://repo.scala-sbt.org/scalasbt/debian /" | sudo tee /etc/apt/sources.list.d/sbt_old.list
   curl -sL "https://keyserver.ubuntu.com/pks/lookup?op=get&search=0x2EE0EA64E40A89B84B2DF73499E82A75642AC823" | sudo -H gpg --no-default-keyring --keyring gnupg-ring:/etc/apt/trusted.gpg.d/scalasbt-release.gpg --import
   sudo chmod 644 /etc/apt/trusted.gpg.d/scalasbt-release.gpg
   sudo apt update
   sudo apt install sbt     
   

   or you can install sbt package from TGZ archives through sdk manager:

   wget https://github.com/sbt/sbt/releases/download/v1.5.5/sbt-1.5.5.tgz     
   sudo tar xzvf sbt-1.5.5.tgz -C /usr/share/     
   sudo update-alternatives --install /usr/bin/sbt sbt
   sdk install sbt
   

Additionally
The ssl of https://keyserver.ubuntu.com/pks/lookup?op=get&search=0x2EE0EA64E40A89B84B2DF73499E82A75642AC823 may not work on 18.04 since it's using a gnupg. we can download the public key using web API. Run:

sudo apt-key adv --keyserver hkps://keyserver.ubuntu.com:443 --recv 2EE0EA64E40A89B84B2DF73499E82A75642AC823

Hope this Helps.

I will first answer your specific questions, ...

1. How can I run an update without getting this error? Is it a matter of somehow removing this repository to get updates from? Is there a way to just skip this repository somehow? (I am listing them all together since they have all the same answer). Yes, see comand sudo mv ... suggested below.
2. Does this package get read by everyone or is it just mine instance b/c I was trying to install a package and now it has added this repo to my list of resources to check for updates? It gets read by everyone, since the changes were introduced in a system-wide location, /etc/apt/sources.list.d/.

... and then expand as follows.

1. If you simply want to update, remove the failing repos from your /etc/apt/sources.list and /etc/apt/sources.list.d/. You could apply several methods to remove ppas added to /etc/apt/sources.list.d/, e.g. simply renaming files /etc/apt/sources.list.d/<myppa>.list to something like <myppa>.list.save.

    $ sudo mv /etc/apt/sources.list.d/sbt.list /etc/apt/sources.list.d/sbt.list.save
   

   This way, you would keep your files just in case. That should be enough to get you going.

2. If you additionally want to update sbt, execute

    $ echo "deb https://repo.scala-sbt.org/scalasbt/debian all main" | sudo tee /etc/apt/sources.list.d/sbt.list
    $ echo "deb https://repo.scala-sbt.org/scalasbt/debian /" | sudo tee /etc/apt/sources.list.d/sbt_old.list
    $ curl -sL "https://keyserver.ubuntu.com/pks/lookup?op=get&search=0x2EE0EA64E40A89B84B2DF73499E82A75642AC823" | sudo apt-key add
    $ sudo apt update
    $ sudo apt install sbt
   

   Commands slightly modified from this official source (apt-get -> apt). Old repos https://dl.bintray.com/loadimpact/debian and https://dl.bintray.com/sbt/debian/sbt-1.5.5.deb are now forbidden. This is similar to what abu-ahmed al-khatiri quotes.

3. If you want to update other packages that belong to failing repos, then please clarify that, so we can help with the specific cases.

1. You installed packages-microsoft-prod.deb from 16.04. You should install the package for the correct version, 20.04.

2. It is often safer to use sudo gdebi <pkg>.deb than sudo dpkg -i <pkg>.deb (as instructed in item 1 above). In this case, given that instructions come directly from MS, it is likely the same.

3. You are hitting a repo for hirsute 21.04, Hit:6 https://packages.microsoft.com/ubuntu/21.04/prod hirsute InRelease (likely in your microsoft-prod.list). You should remove that and add the repo for focal 20.04. Follow these instructions under Ubuntu 20.04 (Focal).

$ uname -a
$ cat /etc/apt/sources.list
$ ls -alFh /etc/apt/sources.list.d
