In some local network, the same country does not mean faster than foreign countries.

Please add an option to test all mirrors.

I've had a few servers have this issue, this one is in singapore. Only thing I can guess is the mirror list is small for this region?

Thanks for this.
I've just installed it on my Kubuntu 20.10 system.
However, I got an error message when I entered the command sudo apt install python-pip python-setuptools python-wheel and then discovered that I actually needed to install the python3-pip package only.
It seems you need to update this information.

I'd like to automate the process of selecting the best mirror via a cron job script. Probably the biggest problem is that I can't print the output of apt-smart --list-mirrors to a file fully. For example, the command apt-smart --list-mirrors > /tmp/mirrors.txt contains only the names of mirror servers - without rank, last updated and bandwidth columns, which I also need so that I can better optimize the choice of the best server, as currently apt-smart --find-best-mirror unfortunately chooses the most up-to-date server, although it may be far too slow compared with another which is several times faster while only a couple of hours behind its last update time.

Currently, -l lists mirrors indexed, and -b just lists the first one and -a selects that first one.

It has happened to me that I want to use 2 or 3, for example, but am constrained to copy and paste the URL and us -c

IMHO, if there was an option akin to -l which prompted for and expected an int as input would then configure the selected one.

-c cannot take an int reliably, as the list of the last l run is not guaranteed to be the same when you run with c but you could bind this to -cl (or -lc) reliably, meaning change based on a list, or of course use a whole new option like C for interactive change which dumps then output of -l then prompts for an int to select one of them and once entered configures it.

Given the ease with which an int can be mis-typed or selected a confirmation step may be warranted, printing the URL selected and asking for confirmation.

When I manually curl https://www.debian.org/mirror/list it connects fine and has no issues.

Each of (1) sudo apt-get update and (2) sudo apt-update yields a message that some package(s) 'can be upgraded' if (and only if) some package(s) can in fact be upgraded. apt-smart a seems not to do that. Thus, any script that, in order to check for possible updates, parses the ouput of 1 or 2 will fail if your program is used instead. See e.g. this snippet of bash that I wrote (or rather that I adapted so as to use apt-smart instead of apt).

Seems like something is wrong here. 😉

I suspect this is because of the switch to the deb822 format for Ubuntu sources:

$ cat /etc/apt/sources.list
# Ubuntu sources have moved to the /etc/apt/sources.list.d/ubuntu.sources
# file, which uses the deb822 format. Use deb822-formatted .sources files
# to manage package sources in the /etc/apt/sources.list.d/ directory.
# See the sources.list(5) manual page for details.

Hey,

thanks for this great tool.

changing the Base Mirror for Bionic works flawless. Unfortunately it doesn't change the Main mirror on Linux Mint Tricia.

When I install the apt smart package but I don't know how to solve this traceback error

In /etc/apt/sources.list.
If I use deb mirror://mirrors.ubuntu.com/mirrors.txt focal main, it fails:

Been noticing lately that some of the fastest mirrors here in western canada fail to get properly evaluated by apt-smart because they redirect to a different domain:

layeronline specifically redirects to https://mirrors.edge.kernel.org/ubuntu/, which is the fastest mirror from my ISP, but apt-smart ignores it. would be great if apt-smart was able to follow redirects and still eval these mirrors.

I'm not sure if it can be done without this but hope there'll be native support for stdin so I can use some code to input a list of URLs directly into apt-smart.

I host an apt server which mirrors content from various deb-based distros like Debian, Kali and Ubuntu.

Ideally I'd like apt-smart to be able to take a parameter for the distro, so that I can check the performance of mirrors for each distro that I mirror.

apt-smart appears to use a hard-coded list of url to determine distro codename:

• /etc/apt/sources.list
• /etc/apt/sources.list.d/official-package-repositories.list

apt-smart should support dynamic sources, scanning .list files under /etc/apt/sources.list.d/.

In all of the boxes in our environment, /etc/apt/sources.list is empty and we use one file per repositories in /etc/apt/sources.list.d

Running apt-smart in our environment, supplying a mirror list file results in apt-smart failing with:
2020-09-30 11:35:09 hostname.domain.com property_manager3[14498] SPAM Setting value of AptMirrorUpdater.get_sources_list_options property to {2: 'Ubuntu-Server 18.04 LTS _Bionic Beaver_ - Release amd64 (20180426)', 4: 'Ubuntu-Server 18.04 LTS _Bionic Beaver_ - Release amd64 (20180426)'} .. 2020-09-30 11:35:09 hostname.domain.com apt_smart.cli[14498] ERROR Encountered unexpected exception! Aborting .. Failed to determine the distribution codename

Would it be a better idea to just get the distro information from /etc/os-release?

I stumbled onto apt-smart while attempting to find solutions to the common "hash sum mismatch" problem with apt-get.

I installed as per instructions and then ran apt-smart -b as can be seen in the below output. However the below error was encountered.

The second time I ran it succeeded and reported mirror http://mirror.solnode.io/ubuntu/releases.

However the third and all subsequent attempts failed with the below error although with different ordinal positions eg byte 0x8d in position 46457, byte 0xe6 in position 53352, byte 0xb0 in position 15208.

Scripts are being run in Ubuntu 18.04 using Vagrant with VirtualBox hosted in Win10.

For me the output of the command apt-smart --list-mirrors is:

And the output of the command apt-smart --find-best-mirror is http://archive.ubuntu.com.
It seems to me that apt-smart is not taking into account the bandwidth (server speed) enough.
I fully agree that, in general, server speed is less important than the time since it was updated.
For instance, the server ranking 7 in the list could even be at the very bottom.
However, I think being merely “1 hour behind” should be considered less important than having less than half the speed.
Therefore, I think the 2nd server in the list should actually be selected as the best mirror.

Unlike Ubuntu having distro-info package which can be got updated by APT, Linuxmint does not have similar package to get up-to-date distro info, at lease I cannot find one. Currently, it relies on me to update the bundled Releases of Linuxmint by run make releases and then publish to github and then release new version of apt-smart. Unfortunately I cannot update it manually in time when new version of Linuxmint is released. This happened when Linux Mint 19.3 Tricia was released several months ago (see #4), obviously it should not happen again. So any suggestion?

P.S. as I said above, if you ran into similar problem, you can run make releases to update bundled Releases to get it work.
(see b7efb9d)

Since I have updated from the main Ubuntu repository, I can only use up to date mirrors without crashing my system.

I need to filter the list generated from apt-smart to only show up to date mirrors.

Maybe the list should be in a different format so I can use it like in ilikenwf/apt-fast#79.

attempting to test apt-smart on the latest Ubuntu LTS, and it fails in the most basic use case, can't seem to detect the release name from /etc/apt/sources.list, even though it's the default config:

note that this could probably be fixed by resolving issue #10.
