Ubuntu – Install oracle-java7-installer through apt-cacher-ng

apt-cacher-ng

I've added the oracle-java7-installer ppa to my apt-cacher-ng server and to my clients. I cannot get it to install.

Any ideas on how I can do this? I think it fails when it tries to download the installation from Oracle. This is what happens when I try to install it:

admin@vgjs001:~$ sudo apt-get install oracle-java7-installer

I was just battling with this, here are my findings for Ubuntu 14.04 Trusty Tahr.

The installer uses apt-config to determine which proxy to use. Specifically if Acquire::http::Proxy::download.oracle.com returns DIRECT to determine whether to use the default proxy of to download directly.

Specifically the install runs

# use apt proxy
APT_PROXIES=$(apt-config shell \
http_proxy Acquire::http::Proxy \
https_proxy Acquire::https::Proxy \
ftp_proxy Acquire::ftp::Proxy \
dl_direct Acquire::http::Proxy::download.oracle.com \
)

And later on

if [ "$dl_direct" = "DIRECT" ]; then
    unset http_proxy
    unset https_proxy
    unset ftp_proxy
fi

If you use the following apt config then the installer with download directly:

Acquire::http::Proxy "http://my.proxy.com:3142";
Acquire::http::Proxy {
        download.oracle.com DIRECT;
};

While this works it is somewhat annoying as the download takes forever and that somewhat defeats the purpose of the proxy.

I found that the installer checks a debconf variable to check whether to use a local file. The property checked is oracle-java8-installer/local and it is a string.

Specifically the installer runs:

db_get oracle-java8-installer/local
if [ -d "$RET" -a -f "$RET"/$FILENAME ]; then

    echo "Installing from local file $RET/$FILENAME"
    cp -f -p "$RET"/$FILENAME ${FILENAME}_TEMP
    mv -f ${FILENAME}_TEMP $FILENAME
else # no local file

So if you have the JDK downloaded and in a directory /jdk/dir then you need to run the following command before running the installer:

sudo debconf-set-selections <<< 'debconf oracle-java8-installer/local string /jdk/dir/'

Note the trailing / on the directory - this is required.

Like this:

$ sudo pbuilder --login --save-after-login
# echo 'Acquire::http { Proxy "http://servername:3142"; };' > /etc/apt/apt.conf.d/02proxy
# exit
$

Alternatively, you could use the --execute option:

$ sudo pbuilder --execute --save-after-exec -- /tmp/setup-apt-proxy.sh

... where /tmp/setup-apt-proxy.sh contains commands to create /etc/apt/apt.conf.d/02proxy.

Ubuntu – Howto use apt-cacher-ng only when available

Something like this should work:

/etc/NetworkManager/dispatcher.d

#!/bin/bash
ip=10.0.1.13
port=3142
nc -w 1 $ip $port
proxy_file="/etc/apt/apt.conf.d/02local_proxy"
if [ $? -eq 0 ]; then
    echo "Acquire::http { Proxy \"http://$ip:$port\"; };" > $proxy_file
    echo 'Acquire::https { Proxy "false"; };' >> $proxy_file
else
    rm -f $proxy_file
fi

Fix permissions

sudo chmod +x /etc/NetworkManager/dispatcher.d/99SetAptProxy

Notes:

The "nc" command tests that it can connect to the 3142 port on the given IP address.
This script is run everytime the networking interfaces are changed by network manager.
Feel free to alter the way that you detect for the proxy, this works for me, but it is a security vulnerability if you install packages on a foreign network, for example.
