Solve apt-get 403 forbidden error in Linux Ubuntu
I’ve been using Ubuntu 16.04 on Oracle VM VirtualBox these days, this morning when I run $ sudo apt-get update to update software, it breaks and I got this error instead:
Seems there is an invalid repository that gives 403 error and causes the problem.
Err:20 http://ppa.launchpad.net/moka/stable/ubuntu xenial/main amd64 Packages
403 Forbidden
We can also run $ sudo apt-get update | grep "Failed" to list failing repositories.
This error might lead other installation processes to fail, for example, installation of RVM(Ruby Version Manager), since $ sudo apt-get update doesn’t work well.
Solution
I decide to temporarily disable the PPA by comment out the source list for the quick fix.
Check installed packages
Use grep to get all enabled binary software sources showing together:
$ grep -r --include '*.list' '^deb ' /etc/apt/sources.list /etc/apt/sources.list.d/
The output might look like this:
In my case, moka-ubuntu-stable-xenial.list is the trouble maker.
Comment out the PPA source
Comment out the content or delete moka-ubuntu-stable-xenial.list and moka-ubuntu-stable-xenial.list.save.
In /etc/apt/sources.list.d/moka-ubuntu-stable-xenial.list:
# deb http://ppa.launchpad.net/moka/stable/ubuntu xenial main
# deb-src http://ppa.launchpad.net/moka/stable/ubuntu xenial main
Now run $ sudo apt-get update, it should work properly, and life goes on.
