Ubuntu10.10 bazaar Installation notes

Bazaar is an open-source distributed version control tool. Distributed version control system (distributed version control system) is a method that does not require the central server to manage the file version. It can also use the central server. Changes to the version can be merged into versions of other users using the distributed version control system for flexible control. In addition, most of its operations are performed locally on the client without network connection, so it is much faster than the centralized server operation. Mainstream distributed version control tools include git, bazaar, and mercurial. Centralized version control tools include SVN, CVS, and VSS.
Bazaar (bzr) is fully developed using python, so it must be supported by python. Download link: wiki.bazaar.canonical.com/download

1. Change the update source
I have tried many update sources, and Netease's speed and stability are very good.
First, back up and update the source table:
Sudo CP/etc/APT/sources. LIST/etc/APT/sources. list_backup
Then open Edit
Sudo Vim/etc/APT/sources. List
Add the following lines and comment out other lines.
Deb http://mirrors.163.com/ubuntu/ maverick main restricted universe multiverse
Deb http://mirrors.163.com/ubuntu/ Maverick-security main restricted universe multiverse
Deb http://mirrors.163.com/ubuntu/ Maverick-Updates main restricted universe multiverse
Deb http://mirrors.163.com/ubuntu/ maverick-proposed main restricted universe multiverse
Deb http://mirrors.163.com/ubuntu/ maverick-backports main restricted universe multiverse
Deb-src http://mirrors.163.com/ubuntu/ maverick main restricted universe multiverse
Deb-src http://mirrors.163.com/ubuntu/ maverick-security main restricted universe multiverse
Deb-src http://mirrors.163.com/ubuntu/ maverick-updates main restricted universe multiverse
Deb-src http://mirrors.163.com/ubuntu/ maverick-proposed main restricted universe multiverse
Deb-src http://mirrors.163.com/ubuntu/ maverick-backports main restricted universe multiverse
Then run refresh list (Be sure to refresh)
Sudo apt-get update

2. Check the required software package
(1) Check the Python version
SHELL> python-v
... Python 2.6.6...
(2) Check the required Python Module

Shell> Python-c "Import crypto" # If no message is displayed, the module is loaded successfully.
Shell> Python-c "Import paramiko" # the error message "cannot be found"
Shell> Python-c "Import celementtree" # the error message "cannot be found"
Shell> Python-c "Import XML. etree. celementtree" # This module is successfully loaded.
Paramiko is an open-source module that enables secure (authentication and encryption) connection to remote computers. It is downloaded at http://www.python.org/pypi/paramiko.
The celementtree module is the c implementation of the elementtree API. Elementtree is the XML library of Python. Download link effbot.org/downloads/javascelementtree.
Download and decompress the package, go to the directory, and run the python installation script.
Shell> Python setup. py install
# If the prompt "python. H" is not found and GCC cannot be compiled, it indicates that python-Dev is not installed.
Install the following package in ubuntu10.10:

Libssl0.9.8 _ 0.9.8o-4_i386.deb
Http://linux.cdpa.nsysu.edu.tw/debian/pool/main/o/openssl/libssl0.9.8_0.9.8o-4_i386.deb
Libssl-dev_0.9.8o-4_i386.deb
Http://ftp.debian.org/debian/pool/main/o/openssl/libssl-dev_0.9.8o-4_i386.deb
Python2.6-dev_2.6.6-5ubuntu1_i386.deb
Http://ftp.isu.edu.tw/pub/Linux/Ubuntu/ubuntu/pool/main/p/python2.6/libpython2.6_2.6.6-5ubuntu1_i386.deb
Then execute again
Shell> sudo Python setup. py install
Compiled and installed successfully.
(3). Check whether the SSH tool is installed. (SSH connection is required for publishing via launchpad.net)
Shell> which SSH
Shell> sudo apt-Get install OpenSSH-Client
