Remove automatically installed software
This article is obsolete and need not work. A newer article is here https://wiki.turris.cz/doc/en/howto/updater#i_installed_a_package_but_it_was_removed
Software in Turris Omnia is handled by updater.sh. There is a set of pre-installed software, which will be reinstalled automatically if manually removed by opkg or via LuCI. This how-to will show you how to remove this software and preserve the removal after updater.sh is executed (manually or automatically).
Removing important packages can make your router inaccessible, for example wifi drivers. Be sure to know what you remove!
Identify packages
First you need to know what packages you want to remove.
- In LuCI: System → Software
- Via ssh connection:
opkg list-installed
Example:
root@turris:~# opkg list-installed 6in4 - 21-2 6rd - 9-2 6to4 - 12-2 acl - 20160519-1 ahcpd - 0.53-2 alsa-lib - 1.1.0-1 at - 3.1.16-2
Modify the configuration
Configuration of updater.sh is located in /etc/updater/user.lua, edits in other files can be replaced with any update or make the update process fail.
Syntax of this file can be found in the github under design/language.txt: https://github.com/CZ-NIC/turris-updater/blob/master/design/language.txt
Uninstall "package" "package" { extra } "package" "package" { extra }
Inside the extra we need to define a priority as the default priority is 50 and the update would still “win” and install the default packages.
This is how the priority is defined in the design document:
priority:: In case of colliding requirements (the same package is required by an ``Install`` command or as a dependency of something), the requirement with the higher priority wins. In case of a draw, an error is reported. The priority defaults to 50 and must be between 0 and 100.
If we want to remove transmission and dependencies to this package it would look like this inside the /etc/updater/user.lua. Only the Uninstall line was added and note the priority is higher than 50.
--[[
A place for user definitions.
Repository "name" "URI" { ca = "file:///etc/ssl/ca.pem", pubkey = "file:///etc/repo.pubkey" }
Install "pkgname" "other"
]]
Uninstall "luci-app-transmission" {priority = 60} "luci-i18n-transmission-cs" {priority = 60} "luci-i18n-transmission-en" {priority = 60} "transmission-daemon-openssl" {priority = 60}
Execute
After the configuration is done run the updater.sh manually and the packages will be removed. Subsequent runs will warn you about the fact that the updater.sh was unable to uninstall the package but it won't trigger email notifications.
