Package management is the process of installing, updating and removing software, tools and libraries.
|
|
On GNU/Linux systems, package management is usually done with a package manager.

# MatterLinux Package Manager
|
|
In a Matter system, package management is generally done with the MatterLinux Package Manager (`matt`).
|
|
`matt` lets you install, remove, update and search different MatterLinux packages across different [pools](/wiki/pools).
|
|
|
|
### Installation
|
|
`matt` should be already installed on a MatterLinux system. However if you want to install `matt` from
|
|
the source, then you should follow [this section](https://git.matterlinux.xyz/matter/matt#installation)
|
|
from the README.
|
|
|
|
> **Note**
|
|
>
|
|
> You should run all the `matt` and related commands as the root user.
|
|
|
|
### Configuration
|
|
Configuration file for `matt` can be found at `/etc/matt/config.ini`. This file is used specify pools and
|
|
configure general settings.
|
|
|
|
Here is the configuration shipped with the MatterLinux 24 releases:
|
|
```
|
|
# configuration file for matt, please see the wiki page for more information
|
|
# https://matterlinux.xyz/wiki/matt
|
|
|
|
tmpdir = /var/lib/matt/temp
|
|
datadir = /var/lib/matt/data
|
|
|
|
[base]
|
|
url = mptp://stable.matterlinux.xyz/base
|
|
# url = mptp://next.matterlinux.xyz/base
|
|
|
|
[desktop]
|
|
url = mptp://stable.matterlinux.xyz/desktop
|
|
# url = mptp://next.matterlinux.xyz/base
|
|
|
|
# [server]
|
|
# url = mptp://stable.matterlinux.xyz/server
|
|
# url = mptp://next.matterlinux.xyz/server
|
|
```
|
|
Lets start by breaking down the first section:
|
|
|
|
- `tmpdir (path)`: Temporary storage directory. Used for extracting temporary files and usually
|
|
this directory will be cleaned after an operation.
|
|
|
|
- `datadir (path)`: Persistent storage directory. Used for storing package databases and pool
|
|
information.
|
|
|
|
Next sections specify the pools. Section name is the pool name, and it **should match with the
|
|
actual pool name**. Pool options are:
|
|
|
|
- `url (URL)`: Pool URL, only `mptp` protocol is supported.
|
|
- `signing (yes/no)`: Enable/disable PGP signature verification for the pool, by default it's enabled.
|
|
|
|
> **Important**
|
|
>
|
|
> Do NOT disable signature verification if you don't know what are you doing! There is no
|
|
> way to confirm the legitimacy of the packages without signature verification!
|
|
|
|
### Options
|
|
`matt` also has a few other options that you specify as an arguments/parameters. You can list these
|
|
options using the `--help` option:
|
|
```
|
|
# matt --help
|
|
```
|
|
You can also list options for specific commands, for example:
|
|
```
|
|
# matt info --help
|
|
# matt list --help
|
|
```
|
|
|
|
### Syncing pools
|
|
To sync remote pool information and package lists, you can use the `sync` command:
|
|
```
|
|
# matt sync
|
|
```
|
|
After syncing remote pools, `matt` will provide public keys for the available pools.
|
|
You can add these keys to your keyring with `gpg`:
|
|
```
|
|
# gpg --receive-keys [fingerprint]
|
|
```
|
|
|
|
### Installing packages
|
|
To install a package, you can use the `install` command:
|
|
```
|
|
# matt install which
|
|
```
|
|
After running this command `matt` will attempt to find, download and verify the `which`
|
|
package, and then install it.
|
|
|
|
You can also install packages from local archives:
|
|
```
|
|
# matt install which_2.21.mpf
|
|
```
|
|
And you can install multiple packages at once:
|
|
```
|
|
# matt install grub systemd linux
|
|
```
|
|
|
|
### Removing/Uninstalling packages
|
|
To remove an installed package, you can use the `remove` command:
|
|
```
|
|
# matt remove which
|
|
```
|
|
You can also remove multiple packages:
|
|
```
|
|
# mp-remove git curl
|
|
```
|
|
|
|
### Updating packages
|
|
You can update all of the installed packages using the `update` command:
|
|
```
|
|
# matt update
|
|
```
|
|
|
|
### Querying packages
|
|
You can get more information about a package by querying it. For example to get
|
|
more information about the `which` package:
|
|
```
|
|
# matt info which
|
|
```
|
|
This will provide the following information about the package:
|
|
|
|
- Name of the package
|
|
- Version
|
|
- Description
|
|
- Size
|
|
- Dependencies
|
|
- If the package is installed
|
|
- If the package is up-to-date
|
|
|
|
### List packages
|
|
You can list all the installed packages with the `list` command:
|
|
```
|
|
# matt list
|
|
```
|
|
|
|
# Other package managers
|
|
It's a really bad idea to use multiple package managers as they may conflict and may result in an
|
|
unstable system. However package managers such as `flatpak` and `snap` offer containerized packages,
|
|
making them possible to use with other package managers. However currently none of these package
|
|
managers are available in the official pools. If you want to use them, you will need to install them
|
|
from the source.
