Q: Moving apt-mirror folders between machines

We have one office with broadband and another one with dialup. My goal is to create a local Ubuntu mirror on the second office. I have used apt-mirror on my local machine, and it downloaded about 130GB of packages. How do I transfer these files to another computer to create a local mirror?

@ruda.almeida cp?

Or, alternatively, scp?

Journeyman Geek

@somequixotic: boris made that. I do not mess with perfection

@OliverSalzburg: wouldn't physically copying the files make more sense?

ruda.almeida

@OliverSalzburg scp'ing 130GB on diaulp? O_o

Oliver Salzburg

@JourneymanGeek I don't know how you physically copy data :D

Journeyman Geek

@OliverSalzburg: there's these things called 'external hard drives'

Oliver Salzburg

@JourneymanGeek And how do you transfer the data onto those "external hard drives"?

Journeyman Geek

I'd guess if you copied over the files to the same location on the other system....

@OliverSalzburg: via this magical thing called 'universal serial bus" Its amazing. Its UNIVERSAL. AND SERIAL. AND might have nothing to do with busses ;p

Oliver Salzburg

@JourneymanGeek Oh, so you connect it via USB and it just sucks the files out of your hard drive? That's cool, tell me more about it

Journeyman Geek

@OliverSalzburg: Its obviously sufficiently advanced technology ;p

Oliver Salzburg

Because, me, being old school, I usually use tools like cp to copy my data onto storage media

But I must have been missing out on some serious technology advances in the past week or something

Journeyman Geek

@OliverSalzburg: I think that scp is network based, and @ruda.almeida assumed you meant transferring all that stuff over a network ;p

so explicitly explicating the possibility of using sneakernet file transfer was necessary!

ruda.almeida

You guys are making me actually LO(notso)L at my work desk.

@ruda.almeida: might also want to check if apt-mirror uses some sort of manifest file in another location

I'd actually copy all the files mentioned here manpages.ubuntu.com/manpages/lucid/man1/apt-mirror.1.html

ruda.almeida

@JourneymanGeek It stores settings on /etc/apt/mirror.list

Oliver Salzburg

You should be using apt-proxy anyway!!!

There, I said it

ruda.almeida

@OliverSalzburg Why?

smarty pants

Oliver Salzburg

@ruda.almeida So you don't mirror data you don't need

I was thinking aptoncd but never mind ;p

Oliver Salzburg

Also, I've read it on the internet

ruda.almeida

@jokerdino My pants doesn't run android, so they're not smart. They are mobile, at least.

jokerdino

@OliverSalzburg I think he needs a cache or something.

and perhaps, he should be asking on SF.

ruda.almeida

I asked on AU because all the machines will be running ubuntu. Well, all the clients, at least.

I might use apt-proxy instead of apt-mirror.

Journeyman Geek

hmm

or use a laptop and just move the whole system physically over....

but thats crazy talk

There's already a squid/pfsense/idontknowthisstuffwell proxy on place, will I need to tweak the settings to make it work?

Q: Best way to cache apt downloads on a LAN?

I have multiple Ubuntu machines at home and a pretty slow internet connection, and sometimes multiple machines need to be updated at once (especially during new Ubuntu releases.) Is there a way where only one of my machines needs to download the packages, and the other machines can use the first...

networking apt proxy cache squid

I don't remember where I read the question that was like "How do I properly set up apt-mirror" and the top answer was like "OMG You should be using apt-proxy!!!"

So, yeah

Journeyman Geek

lol

Oliver Salzburg

It was probably a good one though!

Oh here it is

Q: Is it possible to mirror the apt repositories?

I am a student at Case Western Reserve University, and the bandwidth from the Ubuntu servers to my location is often horrendously bad (on the order of a few hundred bytes per second). Myself and a few friends would like to be able to download the packages once, and have them cached for the rest o...

repository mirrors

Journeyman Geek

I think the problem is physically moving the repos ;p

ruda.almeida

Jul 1, 2013 14:53

@JourneymanGeek Well the actual problem is saving extremely limited bandwidth

Oliver Salzburg

Well, yeah, I guess if you already have 130 GB of (mostly unneeded) packages, that would be a good start to seed your cache with

ruda.almeida

One approach is limiting the bandwidth used by ubuntu updates, and there are (at least) three possible ways of doing that: apt-mirror, apt-proxy and squid-deb-proxy

Journeyman Geek

@ruda.almeida: silly question but would creating a cache on a system, moving the system then mirroring on site make sense?

ruda.almeida

@JourneymanGeek Hm. Only if I did that on a laptop, because carrying a desktop under my arm would raise... questions.

Journeyman Geek

yup

that would simplify the inital move at least

ruda.almeida

Jul 1, 2013 14:59

But then how would I move the cache? Just copy the folders from the laptop? Or set up a new cache on the new site and point that new cache to my lpatopt's cache? Or...? O_o

Oliver Salzburg

@ruda.almeida I've heard you can do that with USB

Journeyman Geek

@ruda.almeida: yes!

@OliverSalzburg: that would make things very easy, yes

Oliver Salzburg

Journeyman Geek

Cause ~~friendship~~ USB is magic

ruda.almeida

@OliverSalzburg I heard you can use USB to travel the entire universe by bus. Or something.

If that ain't magic...
