Last build installation problem

[psanzm]

Hi, first at all thanks for your amazing work, it's just what i was looking for.

I running an VPS in DigitalOcean with Ubuntu 14.04.3 and when I build the docker get this error:

root@smarty:~/dockerflix# ./build.sh Sending build context to Docker daemon 119.3 kB Sending build context to Docker daemon Step 0 : FROM phusion/baseimage:0.9.16 ---> 5a14c1498ff4 Step 1 : MAINTAINER trick77 jan@trick77.com https://trick77.com/ ---> Running in f07f15c8bc6d ---> 17575ff2290f Removing intermediate container f07f15c8bc6d Step 2 : RUN apt-get -qq update ---> Running in 9026ddf7cba8 W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/trusty/InRelease

Building dependency tree... Reading state information... Package python-software-properties is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source However the following packages replace it: software-properties-common

E: Package 'python-software-properties' has no installation candidate The command '/bin/sh -c apt-get -y install python-software-properties && add-apt-repository ppa:dlundquist/sniproxy && apt-get update && apt-get -y install sniproxy' returned a non-zero code: 100

The error seems the package python-software-properties but if I run in the VPS "apt-cache search python-software-properties" I have no problem finding that.

Any clue about how to fix this?

Thanks in advance for your response,

Regards, Pedro.

Thanks! Failed to fetch http://archive.ubuntu.com/ubuntu/dists/trusty-security/Release.gpg Could not resolve 'archive.ubuntu.com'

This could have been a temporary problem in the VPS or there's a problem with name the DNS in the VPS. It's not related to Dockerflix. You could ask DO for support if you don't know how to solve it.

Hi trick and thanks for reply back so quickly!

The VPS resolves correctly

root@smarty:~# nslookup archive.ubuntu.com Server: 127.0.0.1 Address: 127.0.0.1#53

Non-authoritative answer: Name: archive.ubuntu.com Address: 91.189.91.14 Name: archive.ubuntu.com Address: 91.189.91.13 Name: archive.ubuntu.com Address: 91.189.92.200 Name: archive.ubuntu.com Address: 91.189.91.15 Name: archive.ubuntu.com Address: 91.189.91.23 Name: archive.ubuntu.com Address: 91.189.92.201 Name: archive.ubuntu.com Address: 91.189.91.24 Name: archive.ubuntu.com Address: 91.189.88.149

And the command "apt-get -qq update" runs without problems, it't seems to be only in the docker contanier during the building process.

Again, thanks for your reply.

It's because Docker can't reach your local DNS server.

[psanzm]

Ok, i will investigate further because the local dns server is working without problems. I use myself as dns server in my local pc.

I'll keep you updated if I find something else.

The Docker container has its own network and is connected to your VPS's network using a bridge. Localhost in the container != localhost in the VPS.
