Ubuntu Local Source Creation and local source maintenance (delete expired or repeated software packages)

1. all software packages installed from the software repository are cached in the local/var/cache/apt/archives file. In addition, it is very troublesome to reinstall the Chinese Language Pack on the Internet after Ubuntu is installed. In addition, it is very troublesome to install the copyright driver of MP3 and other audio and video programs every time. Therefore, it is necessary to create the local source. To get back to business, you must first install

1. Make software source

Anyone who has been using Ubuntu Lucid Lynx (Ubuntu 10.04) For A While should know that all software packages installed from the software repository will be locally

/Var/cache/apt/archives

. In addition, it is very troublesome to reinstall the Chinese Language Pack on the Internet after Ubuntu is installed. In addition, it is very troublesome to install the copyright driver of MP3 and other audio and video programs every time. Therefore, it is necessary to create the local source.

To put it bluntly, you must first install the software package dpkg-dev.

# Sudo apt-get install dpkg-dev

After configuration, create a directory under/as the storage location of the software package, or place it in any location on the hard disk.

Copy all packages in/var/cache/apt/archives to this folder.

Run the following command to create the software source:

# Sudo dpkg-scanpackages/software/dev/null | gzip>/software/Packages.gz

After the system scans all the software packages, it returns to the command line and generates a compressed file named packages.gz in the softwarefolder, which contains the package information in the folder and its dependencies.

2. Use software sources

Link

# Sudo gedit/etc/apt/sources. list

Delete all content, add

Deb file: // software/

Save.

Open the terminal and enter

# Sudo apt-get update

To update the local package list

Then you can use the apt-get command to install the software package contained in the local source or directly execute it like me.

# Sudo apt-get dist-upgrade

Command to update the system. If you are more lazy, enter the following command:

# Sudo apt-get update; sudo apt-get dist-upgrade
