La liste des serveurs miroirs est récupérée par la bibliothèque Python (l'outil get_server_list La procédure est définie dans /usr/lib/python3/dist-packages/aptsources/distro.py et appelé de /usr/lib/python3/dist-packages/softwareproperties/gtk/SoftwarePropertiesGtk.py ).
La solution consiste à utiliser l'outil nommé apt-mirror-updater . Il peut être installé à partir de pip / pip3 :
sudo pip3 install apt-mirror-updater
Fonctionnalité :
Utilisation : apt-mirror-updater [OPTIONS].
Le programme apt-mirror-updater automatise le miroir robuste apt-get pour Debian et Ubuntu en permettant la découverte des miroirs disponibles miroirs disponibles, le classement des miroirs disponibles, le basculement automatique entre les miroirs et une mise à jour robuste de la liste des paquets.
Options prises en charge :
-r, --remote-host=SSH_ALIAS
Operate on a remote system instead of the local system. The SSH_ALIAS
argument gives the SSH alias of the remote host. It is assumed that the
remote account has root privileges or password-less sudo access.
-f, --find-current-mirror
Determine the main mirror that is currently configured in
/etc/apt/sources.list and report its URL on standard output.
-b, --find-best-mirror
Discover available mirrors, rank them, select the best one and report its
URL on standard output.
-l, --list-mirrors
List available (ranked) mirrors on the terminal in a human readable format.
-c, --change-mirror=MIRROR_URL
Update /etc/apt/sources.list to use the given MIRROR_URL.
-a, --auto-change-miroir
Discover available mirrors, rank the mirrors by connection speed and update
status and update /etc/apt/sources.list to use the best available mirror.
-u, --update, --update-package-lists
Update the package lists using `apt-get update', retrying on failure and
automatically switch to a different mirror when it looks like the current
mirror is being updated.
-x, --exclude=PATTERN
Add a pattern to the mirror selection blacklist. PATTERN is expected to be
a shell pattern (containing wild cards like `?' and `*') that is matched
against the full URL of each mirror.
-m, --max=COUNT
Don't query more than COUNT mirrors for their connection status
(defaults to 50). If you give the number 0 no limit will be applied.
Because Ubuntu mirror discovery can report more than 300 mirrors it's
useful to limit the number of mirrors that are queried, otherwise the
ranking of mirrors will take a long time (because over 300 connections
need to be established).
-v, --verbose
Increase logging verbosity (can be repeated).
-q, --quiet
Decrease logging verbosity (can be repeated).
-h, --help
Show this message and exit.
Il permet donc de trouver le meilleur miroir et de l'appliquer à /etc/apt/sources.list :
sudo apt-mirror-updater --auto-change-mirror
Il permet également de sélectionner un miroir par URL et de l'appliquer à l'un des éléments suivants /etc/apt/sources.list :
$ apt-mirror-updater --list-mirrors

puis sélectionnez le miroir à la main :
sudo apt-mirror-updater -c "http://mirror.timeweb.ru/ubuntu"
