Environment: Ubuntu 18.04

1. Acquire license certification

Get the document from darwin source, use "Alt+Ctrl+T" to open the command window, enter

$ssh-keygen

All the way back, back, back

You can see that the generated id_rsa file, at / home/wangcen/.ssh/id_rsa location (different computer location, please note for yourself), you need to copy this file to Junzheng's staff to add permission before you can continue source synchronization.But the file is hidden, so we do the following:

1 Enter the folder where the file is located

$cd /home/wangcen/.ssh

(2) Extract the file

$ls
$cp id_rsa.pub ~/

Then we can see that there is this id_in the home folderRsa.pubFile,

Next, give this file to Junzheng's staff for permission certification, and then we can continue.

2. Repo Tool Download (you can download repo tools by typing the following four commands in sequence)

$mkdir project_workspace
$cd project_workspace
$wget http://git.ingenic.com.cn:8082/bj/repo
$chmod +x repo

3. Source synchronization

$./repo init -u ssh://sz_halley2@58.250.243.8:29418/mirror/darwin/project/manifest.git

Error one occurred:
Unable to negotiate with xxx.xxx.xxx.xxx port 29418: no matching key exchange method found.
Their offer: diffie-hellman-group1-sha1

Solution (create one if there is no config file):

$sudo vi /etc/ssh/ssh_config

In ssh_In the config file, enter:

Host *
KexAlgorithms +diffie-hellman-group1-sha1

Error 2 occurred:

Solution (remember to force repo file deletion (enter rm.repo-RF) every time an error occurs before you can enter source link):

$ git config --global user.email "Enter your mailbox"
$ git config --global user.name "Enter your name"
$ rm .repo -rf

Error three occurred:
The following errors were made:
Unable to negotiate with xxxxxxxx: no matching cipher found. Their offer: aes128-cbc,3des-cbc,blowfish-cbc,aes192-cbc,aes256-cbc
fatal: Unable to read remote repository
no matching cipher found. Their offer: aes128-cbc,3des-cbc,blowfish-cbc,aes192-cbc,aes256-cbc

Solution:

$sudo vi /etc/ssh/ssh_config

Find the line:

#   Ciphers aes128-ctr,aes192-ctr,aes256-ctr,arcfour256,arcfour128,aes128-cbc,3des-cbc,blow fish-cbc,cast128-cbc,aes192-cbc,aes256-cbc,arcfour

Add the following line to the back (without #):

Ciphers aes128-ctr,aes192-ctr,aes256-ctr,aes128-cbc,3des-cbc,aes192-cbc,aes256-cbc

Save it.
After resolving the above problems, enter the following source synchronization code to synchronize successfully.

$ ./repo init -u ssh://sz_halley2@58.250.243.8:29418/mirror/darwin/project/manifest.git
Get http://git.ingenic.com.cn:8082/gerrit/android/repo.git
$./repo sync
