apt downloading packages from ... some ... server ?

[andy55]

I have the following apt setup:

Code: Select all

$ cat /etc/apt/sources.list
deb [arch=amd64] http://ftp.fi.debian.org/debian/ testing main contrib non-free
deb [arch=amd64] http://ftp.fi.debian.org/debian/ testing-updates main contrib non-free

but when running apt update/upgrade it downloads some packages from another server:

Code: Select all

...
Get:4 http://ftp.fi.debian.org/debian testing/main amd64 libasan6 amd64 11.3.0-8 [2,050 kB]
Get:6 http://ftp.fi.debian.org/debian testing/main amd64 libgcc-11-dev amd64 11.3.0-8 [2,360 kB]
Get:5 http://chuangtzu.ftp.acc.umu.se/debian testing/main amd64 gcc-11 amd64 11.3.0-8 [18.2 MB]
Get:7 http://ftp.fi.debian.org/debian testing/main amd64 libtsan0 amd64 11.3.0-8 [2,018 kB]
...

Why the

chuangtzu.ftp.acc.umu.se

is being used ?

Anything in /etc/apt/sources.list.d?

It's a Mirror in Sweden. Their servers are named after Chinese philosophers. You are not being redirected to China.

I know it is Sweden.

But there are two problems here:
- if I specify in the apt server X I thought it is respected ?
- why package P1 it is being downloads from X and P2 from Y ? Is P2 missing on X ?

http://ftp.fi.debian.org = http://mirror.accum.se = http://chuangtzu.ftp.acc.umu.se

The server network, ftp.acc.umu.se, you are downloading from is quite large with several front ends. Small files are served from the front end but larger files move the requests to the backend of the network where the larger packages are held for download. You never leave their network. That server front end also serves gnome and ubuntu to give you a scope of the size.

Thanks @donald - that makes sense.
