Ubunutu + Dokku + Docker apt-get update issue

I installed the dokku-apt plugin, which runs the command “apt-get update” in a deploy script. When running during the deploy process, this line results in the following error:

Err: quantal/main amd64 Packages 404 Not Found [IP: 80]

However, when I simply log into my server and run “apt-get update”, everything works fine.

Anyone know why?

This has been confirmed to be a bug in Dokku. You can view the issue on GitHub.

Upgrading buildstep will resolve the problem:

$ git clone
$ cd buildstep
$ git pull origin master
$ sudo make build

Quick and dirty hack:

  • Copy all sources from digitalocean server (/etc/apt/sources.list) to your apt-repositories
  • Go to /var/lib/dokku/plugins/dokku-apt
  • Replace in pre-build:
if [ -f $DIR/apt-repositories ]; then
    apt-get update
    apt-get install -y software-properties-common
    cat "$DIR/apt-repositories" | while read repository; do
        add-apt-repository -y "\$repository"

with the following:

if [ -f $DIR/apt-repositories ]; then
    cat $DIR/apt-repositories > /etc/apt/sources.list
    apt-get update
    apt-get install -y software-properties-common
  • Update dokku plugins (not sure, if required):
cd -
dokku plugins-install
  • Push!

Yep, I have the same error. Everything until quantal-security works fine, then starting with quantal/main amd64 the 404s come in spades. The server itself, as it seems, uses different set of repositories, so apt-get update works fine.

Edit: You may try to use sources from /etc/apt/sources.list on your server, by specifying those in apt-repositories, in your repo.
