internetupgradewget
I wanna upgrade my Ubuntu from 11.04 to 12.04,but the internet is so slow when I use Synaptic or Update Manager,because they only make one connection to download packages like wget.( 6 ~ 7kbps ).
but when I use axel to download my speed is 160 kbps.
now I'm upgrading and it take 6days to be compelet by this speed.
is there any way to force it to use more than one connection to get packages?
From what I know the update process is as folows:
In other words, if your connection is interrupted, nothing will change to your system because the first step is not finished. Step two is executed if and only if step 1 was successful.
This is the upgrade manager you'll see. Note how first the new channels are fetched, then the new pacakges, only then to proceed to install them.
Just before the actual fetching of the packages starts, you will get the following dialogue box which confirms my answer:
Note: You should not be worried so much about your connection, but about making sure your power source stays alive. If you switch off your computer or your power source whilst the update is ongoing, then your system will be messed up.
Also as a general note: always keep two external backups of all your files before you upgrade and do not upgrade a production system without having a large amount of time and knowledge about what to do if something in the upgrade did not go as expected.
For the rest, welcome to 14.04.
I fixed it! This is how:
I followed https://www.itzgeek.com/how-tos/linux/debian/how-to-disable-ipv6-on-debian-9-ubuntu-16-04.html (Method 1) to disable IPv6 on my server.
Then I removed the DNS servers from the /etc/resolv.conf file by removing the nameserver lines.
Then I installed network-manager by using: apt -y install network-manager
Then I disabled other DNS services by fully opting-out from the NetworkManager by typing:
echo -e "[main]\ndns=none" > /etc/NetworkManager/conf.d/no-dns.conf
systemctl restart NetworkManager.service
rm /etc/resolv.conf
Then I disabled and removed systemd-resolved by typing the following:
sudo systemctl disable systemd-resolved.service
sudo systemctl stop systemd-resolved
Then I have put the following line in the [main] section of my /etc/NetworkManager/NetworkManager.conf file:
dns=default
Then I removed /etc/resolv.conf by typing: rm /etc/resolv.conf
Then I finally restarted network-manager by typing: sudo service network-manager restart
Now my internet speed is the normal one :)
This also works on Debian.
For CentOS: All what you have to do is to disable IPv6, and remove the nameserver lines from /etc/resolv.conf only.

Yes it is, using a program that is called apt-fast, How to from this site http://www.webupd8.org/2010/08/you-can-now-install-apt-fast-from-ppa.html
First run theses commands in terminal, put one line in at a time and hit enter, enter password when prompted.
After it is installed you can use
apt-fastjust likeapt-getakasudo apt-fast upgradeThey say it is a full syntax replacement, so try it with any situation you would use apt-get I haven't had it fail yet, but if something does go wrong try
apt-fast clean, by default it has like 4 connections, I read here that you can customize it for more here http://nvarona.blogspot.com/2011/01/accelerating-ubuntu-apt-get.html
