The following guide will provide you with some information on how to improve Ubuntu's repository download speed by selecting the closest, that is, possibly fastest mirror relative to your geographical location.
The following guide will provide you with some information on how to improve Ubuntu's repository download speed by selecting the closest, that is, possibly fastest mirror relative to your geographical location.
1. Country Code
The simplest approach is to make sure that your Ubuntu mirror defined within/etc/apt/sources.list
includes a relevant country code appropriate to your location. For
example, below you can find a official United States Ubuntu mirror as
found in /etc/apt/sources.list
:
deb http://us.archive.ubuntu.com/ubuntu/ xenial main restrictedIf you are not located in United States simply overwrite the
us
country code with appropriate code of your country. That is, if your are located for example in Australia update your /etc/apt/sources.list
file for all entries as:
deb http://au.archive.ubuntu.com/ubuntu/ xenial main restricted
2. Use mirror protocol
Using mirror protocol as part of your/etc/apt/sources.list
entry will instruct apt command to fetch mirrors located within your
country only. In order to use mirror protocol update all lines within /etc/apt/sources.list
file from the usual eg.:
deb http://us.archive.ubuntu.com/ubuntu/ xenial main restrictedto:
deb mirror://mirrors.ubuntu.com/mirrors.txt xenial main restrictedRepeat the above for all relevant lines where appropriate. Alternatively, use
sed
command to automatically edit your /etc/apt/sources.list
file. Update the below sed
command where appropriate to fit your environment:
$ sudo sed -i -e 's/http:\/\/us.archive/mirror:\/\/mirrors/' -e 's/\/ubuntu\//\/mirrors.txt/' /etc/apt/sources.list
3. Manual apt mirror selection
The above solutions look easy and they might just work for you. However, the mirror selected by apt may not be the fastest as it can be burdened by high latency. In this case you may try to choose your mirror manually from the list of mirrors located within your country. Usewget
command to retrieve the list. The below wget
command will retrieve apt ubuntu mirrors related to your country. Example:
$ wget -qO - mirrors.ubuntu.com/mirrors.txt http://mirror.netspace.net.au/pub/ubuntu/ http://mirror.internode.on.net/pub/ubuntu/ubuntu/ http://mirror.overthewire.com.au/ubuntu/ http://mirror.aarnet.edu.au/pub/ubuntu/archive/ http://mirror.tcc.wa.edu.au/ubuntu/ http://ubuntu.mirror.serversaustralia.com.au/ubuntu/ http://ftp.iinet.net.au/pub/ubuntu/ http://ubuntu.mirror.digitalpacific.com.au/archive/ http://mirror.waia.asn.au/ubuntu/ http://ubuntu.uberglobalmirror.com/archive/ http://mirror.as24220.net/pub/ubuntu/ http://mirror.as24220.net/pub/ubuntu-archive/Based on your experience select the best mirror and alter your
/etc/apt/sources.list
apt configuration file appropriately.
4. Choosing the fastest mirror with netselect
This solution is preferred, as it guarantees the fastest mirror selection. For this we are going to usenetselect
command. The netselect
package is not available within Ubuntu's standard repository by
default, so we will need to borrow it from Debian stable repository:
$ sudo apt-get install wget $ wget http://ftp.au.debian.org/debian/pool/main/n/netselect/netselect_0.3.ds1-26_amd64.deb $ sudo dpkg -i netselect_0.3.ds1-26_amd64.debOnce you have the
netselect
command available on your
Ubuntu system use it to locate the fastest mirror based on the lowest
icmp latency. The netselect output will be relative to your location.
The below example output will show top 20 apt Ubuntu mirrors ( if
available ):
$ sudo netselect -s 20 -t 40 $(wget -qO - mirrors.ubuntu.com/mirrors.txt) 12 http://ubuntu.uberglobalmirror.com/archive/ 20 http://ubuntu.mirror.serversaustralia.com.au/ubuntu/ 21 http://ubuntu.mirror.digitalpacific.com.au/archive/ 38 http://mirror.aarnet.edu.au/pub/ubuntu/archive/ 39 http://mirror.overthewire.com.au/ubuntu/ 45 http://mirror.internode.on.net/pub/ubuntu/ubuntu/ 121 http://mirror.netspace.net.au/pub/ubuntu/ 148 http://mirror.waia.asn.au/ubuntu/ 152 http://mirror.as24220.net/pub/ubuntu-archive/ 162 http://mirror.tcc.wa.edu.au/ubuntu/ 664 http://archive.ubuntu.com/ubuntu/ 664 http://archive.ubuntu.com/ubuntu/ 3825 http://archive.ubuntu.com/ubuntu/ Only found 13 hosts out of 20 requested.Alter manually your
/etc/apt/sources.list
file to reflect the above netselect
results or use sed
command, where the lower score number on the left represents a higher mirror transfer rate. Example:
$ sudo sed -i 's/http:\/\/us.archive.ubuntu.com\/ubuntu\//http:\/\/ubuntu.uberglobalmirror.com\/archive\//' /etc/apt/sources.list
5. Comparing results
The following are myapt-get update
command results, while located within Australia:
US MIRROR ( http://us.archive.ubuntu.com/ubuntu ): Fetched 23.1 MB in 20s (1148 kB/s) MIRROR protocol( mirror://mirrors.ubuntu.com/mirrors.txt): Fetched 23.1 MB in 4min 45s (81.0 kB/s) AU MIRROR ( http://au.archive.ubuntu.com/ubuntu ): Fetched 23.1 MB in 12s (1788 kB/s) NETSTAT Auto-Selected ( http://ubuntu.uberglobalmirror.com/archive ): Fetched 23.1 MB in 6s (3544 kB/s)
