apt proxy failures

[Andy Doan]

We've been seeing an occassionally weird issue when setting the apt proxy. It looks like:

root@master:~# [rc=0]: cp -L /etc/resolv.conf /mnt/testrootfs/etc
root@master:~# [rc=0]: mount --rbind /dev /mnt/testrootfs/dev
root@master:~# [rc=0]: chroot /mnt/testrootfs sh -c 'export http_proxy=http://1 92.168.1.10:3128/'
root@master:~# [rc=0]: chroot /mnt/testrootfs echo 'Acquire::http::proxy "http: //192.168.1.10:3128/";' > /etc/apt/apt.conf.d/30proxy
root@master:~# [rc=0]: chroot /mnt/testrootfs cat /etc/apt/apt.conf.d/30proxy
cat: /etc/apt/apt.conf.d/30proxy: No such file or directory

A real example of this is here:
 http://validation.linaro.org/lava-server/scheduler/job/23773/log_file

Its happening enough (and fairly consistently on snowballs) that I think we should try and understand this. One thing I notice in the log file above was that it took a few retries to download the root.tar.gz. So I wonder if the 30proxy is just a symptom and not the root issue.

I should also add. Alexander thinks the way we are doing this is wrong. He thinks that rather than setting 30proxy, we should run instead run apt-get differently:

 apt-get -oAcquire:http:proxy=http://192.168.1.10:3128

There's a high reproduce possibility on Snowball. Report "E: Syntax error /etc/apt/apt.conf.d/30proxy:1: Extra junk at end of file"

here's an example of a test showing this working in staging:
