Tambah dan hapus saluran pembaruan dengan cara terminal yang mudah

15

Saya tahu ada GUI di Ubuntu Software & Updatesuntuk mengaktifkan saluran pembaruan

pembaruan
diusulkan
backports
keamanan

seperti yang ditunjukkan pada tangkapan layar ini:

Saya mencari cara mudah untuk melakukan ini dari dalam terminal menggunakan perintah seperti

sudo apt-add-update enable updates
sudo apt-add-update enable proposed
sudo apt-add-update enable backports
sudo apt-add-update enable security

sudo apt-add-update disable updates
sudo apt-add-update disable proposed
sudo apt-add-update disable backports
sudo apt-add-update disable security

dan satu hal lagi

sudo apt-add-update enable default

sudo apt-add-update disable default

Beberapa contoh untuk pemahaman yang lebih baik

Kosong sources.list
- cat /etc/apt/sources.list
```
<empty>
```
- sudo apt-add-update enable security
```
<empty>
```

Satu repositori yang diaktifkan ( main)

cat /etc/apt/sources.list

deb http://archive.ubuntu.com/ubuntu wily main

sudo apt-add-update enable security

deb http://archive.ubuntu.com/ubuntu wily main
deb http://archive.ubuntu.com/ubuntu wily-security main

Dua atau lebih repositori yang diaktifkan dalam satu atau dua baris

cat /etc/apt/sources.list

deb http://archive.ubuntu.com/ubuntu wily main universe

atau

deb http://archive.ubuntu.com/ubuntu wily main
deb http://archive.ubuntu.com/ubuntu wily universe

sudo apt-add-update enable security

deb http://archive.ubuntu.com/ubuntu wily main universe
deb http://archive.ubuntu.com/ubuntu wily-security main universe

atau

deb http://archive.ubuntu.com/ubuntu wily main
deb http://archive.ubuntu.com/ubuntu wily-security main
deb http://archive.ubuntu.com/ubuntu wily universe
deb http://archive.ubuntu.com/ubuntu wily-security universe

Dengan deb-srcentri

cat /etc/apt/sources.list

deb http://archive.ubuntu.com/ubuntu wily main universe
deb-src http://archive.ubuntu.com/ubuntu wily main universe

sudo apt-add-update enable security

deb http://archive.ubuntu.com/ubuntu wily main universe
deb-src http://archive.ubuntu.com/ubuntu wily main universe
deb http://archive.ubuntu.com/ubuntu wily-security main universe
deb-src http://archive.ubuntu.com/ubuntu wily-security main universe

Dengan deb-srcentri tidak aktif

cat /etc/apt/sources.list

deb http://archive.ubuntu.com/ubuntu wily main universe
# deb-src http://archive.ubuntu.com/ubuntu wily main universe

sudo apt-add-update enable security

deb http://archive.ubuntu.com/ubuntu wily main universe
# deb-src http://archive.ubuntu.com/ubuntu wily main universe
deb http://archive.ubuntu.com/ubuntu wily-security main universe

The defaulthal

cat /etc/apt/sources.list

deb http://archive.ubuntu.com/ubuntu wily-security universe

sudo apt-add-update enable default

deb http://archive.ubuntu.com/ubuntu wily universe
deb http://archive.ubuntu.com/ubuntu wily-security universe

Hanya satu entri dan disabletindakan
- cat /etc/apt/sources.list
```
deb http://archive.ubuntu.com/ubuntu wily-security universe
```
- sudo apt-add-update disable security
```
<empty>
```

Server yang berbeda atau sama untuk repositori yang berbeda atau yang sama, saling menghormati setiap server

cat /etc/apt/sources.list

deb http://archive.ubuntu.com/ubuntu wily universe
deb http://us.archive.ubuntu.com/ubuntu wily main

sudo apt-add-update enable security

deb http://archive.ubuntu.com/ubuntu wily universe
deb http://us.archive.ubuntu.com/ubuntu wily main
deb http://archive.ubuntu.com/ubuntu wily-security universe
deb http://us.archive.ubuntu.com/ubuntu wily-security main

Rilis Ubuntu yang berbeda untuk repositori yang berbeda, hormati setiap rilis

cat /etc/apt/sources.list

deb http://archive.ubuntu.com/ubuntu wily main universe
deb http://archive.ubuntu.com/ubuntu trusty main

sudo apt-add-update enable security

deb http://archive.ubuntu.com/ubuntu wily main universe
deb http://archive.ubuntu.com/ubuntu trusty main
deb http://archive.ubuntu.com/ubuntu wily-security main universe
deb http://archive.ubuntu.com/ubuntu trusty-security main

AKP atau sumber paket lain (bukan kanonik) di dalam sources.list?

Mengabaikan!
Jangan mengubah protokol, misalnya https, http, tor, ...

Pembaruan 27 Nov 2015 :

Versi kedua dari skrip masih membuat saya tidak puas dengan keasrian kode sumber dan fakta bahwa saya harus menggunakan beberapa alat yang berbeda. Karenanya saya mencoba menulis ulang skrip hanya dalam AWK.

Script baru menggunakan AWK murni, dan mematuhi persyaratan dengan jauh lebih baik. Pada dasarnya itu menulis ulang /etc/apt/sources.listsetiap kali dijalankan.

Setelah menjalankan skrip, pembaruan diperlukan, oleh karena itu jalankan sudo apt-get updatesetelah skrip berhasil keluar.

File tersebut harus memiliki izin yang dapat dieksekusi diaktifkan chmod +x add-update.awkdan disimpan di salah satu direktori yang terdapat dalam $PATHvariabel. Terutama disarankan untuk menyimpan skrip ke $HOME/binfolder (yang juga harus ditambahkan ke$PATH variabel).

Pencadangan /etc/apt/sources.listfile asli tidak diperlukan tetapi sangat disarankan. Untuk membuat cadangan file, lakukan

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

Pemakaian:

sudo ./add-update.awk -v ACTION=[enable|disable|help] -v SOURCE=[updates|backports|security|proposed]

Pemakaian:

## testing

apt-add-update  enable|disable  default|security|updates|proposed|backports  [file]


## real

sudo  apt-add-update  enable|disable  default|security|updates|proposed|backports

Poin utama di sini:

Saya parsing file karena saya sendiri sedang mencari beberapa opsi lain.

Memeriksa apakah ada mirror, baik yang resmi termasuk (rilis lama, port) atau mirror lain yang disediakan oleh komunitas yang dimuat dari python-aptpaket (ini berisi file dengan semua mirror).
```
/usr/share/python-apt/templates/Ubuntu.mirrors
```
Selalu simpan URI resmi dalam file. Jadi, bahkan dengan semua yang dinonaktifkan, itu akan menjaga baris komentar untuk pengaturan kegigihan. Ini menyelesaikan garis ke minimum dengan jenis penyortiran alfabet, url, dist, comp.
Mencetak ke stdout jika mendapat file input sebagai argumen ke-3 atau tidak ada izin untuk menulis /etc/apt/sources.list
Tidak mendukung [ options ]suka [ arch=amd64 ].
Menjatuhkan disable default yang saya mewajibkan pengguna untuk menentukan apa yang harus dinonaktifkan.
Saya tidak suka opsi terakhir (9), karena saya sendiri sengaja mencampur repo. Jadi mereka harus diperlakukan sebagai repositori pihak ke-3.

Unduh: dengan set uji lengkap.

Anda dapat melakukannya dengan cara yang sangat sederhana dengan menggunakan add-apt-repository.

Misalnya, Anda dapat menambahkan proposeddengan

sudo add-apt-repository "http://archive.ubuntu.com/ubuntu/ $(lsb_release -sc)-proposed restricted universe multiverse main"

Itu akan menambah debdan deb-srcbaris ke /etc/apt/sources.list. Tetapi baris sumber akan dikomentari.

Jika Anda menjalankan add-apt-repositorydengan -sparameter, itu tidak akan berkomentar deb-src.

Anda dapat mengaktifkannya securitydengan

sudo add-apt-repository "http://security.ubuntu.com/ubuntu/ $(lsb_release -sc)-security restricted universe multiverse main"

Ya, saya bisa melakukannya dengan cara ini. Tetapi saya akan membutuhkan repositori dan server dan bukan hanya sebuah add securityatau add proposed.

@ AB Tidak jelas apa yang Anda inginkan. Anda perlu perintah yang lebih sederhana atau apa? Perintah ini melakukan apa yang Anda lakukan di GUI.

Seperti dijelaskan dalam Pertanyaan: "Saya mencari cara mudah untuk melakukan ini dari dalam terminal menggunakan perintah seperti ... Mungkin sesuatu seperti: sudo apt-add-update security"

— AB

Dan apa yang salah dengan perintah ini? Itu panjang? Anda dapat memperbarui dengan sudo apt-get update. Dan cukup mudah untuk mempersingkat perintah.

Ya sudo add-apt-repository "http://archive.ubuntu.com/ubuntu/ wily-proposed restricted universe multiverse main"terlalu lama untuk mendukung orang lain. Saya harus mengambil repositori yang sudah ada sebelumnya dan server yang digunakan.
