It’s deployments that turn out to be wrong.
Litetouch deployment failed, return code = -2147467259 0x80004005
It’s been a long day, but I finally got the results back. Write it down.
Method 1
On your Windows 7 reference PC, open the registry editor. Navigate to the HKLM \ system \ settings. Look for a multi-string value called “CloneTag”. I’m guessing it’s not there. Add a new multistring value named “CloneTag”. The actual value doesn’t matter. I’m not sure if the case on the name matters, so I mimicked the error message. Export the HKLM\system\settings key and save it to the .reg file. Edit the .reg file and remove all other entries except for the CloneTag value.
Run cscript to start the task sequence selector. Select your Sysprep and capture the Task Sequence. Enter your credentials and start.
When it gets to the part where the sysprep is executed, run the .reg file to quickly import the CloneTag multi-string value. If you see that it continues to sport, then you should be clear.
Method 2
Go to the Scripts folder in your DS box and create a backup of the LTISysprep file somewhere on your desktop so you will have a copy and if anything goes wrong open the LTISysprep file with Notepad and remove osshell. MACHINE\System\Setup\CloneTag’ line off and save the file to update your deployment share continues by logging in to the referenced computer and on your DS machine.
Run the LiteTouch script to capture p_w_picpath on
Method 3.
The reason for this failure is that the registry key CloneTag under HKLM\system\settings was deleted during sysprep startup:
1.
Enter your sysprep and capture the task sequence, execute sysprep, Options tab, Add, Registry Settings. Enter “System\Settings” in the “Key” box, and enter the CloneTag in the “Value Name” box, and place the “Value” in the CloneTag. ” box is left blank. The whole step is to add the registry entry back to the HKLM\system\setup after the sysprep is complete.
2. (Same approach as suggested by Jimmy lami)
You can also modify the script to prevent deletion of registry entries. Go to the deploymentshare folder and look for the script named LITSysprep in the scripts folder. Right-click on edit to make changes in the script. You can remove the oShell.RegDelete “HKEY_LOCAL_MACHINE\SystemSetup\CloneTag” or you may want to add. // infront to convert it to a comment.

vscode import numpy error：DLL load failed: The specific module could not be found
An error description
- anaconda prompt, import numpy in normal vscode, import numpy error: DLL load failed
Error reason
Vscode failed to properly initialize the environment variable
The solution
Open the vscodesettings.json file
(type) CTRL + SHIFT + P
(search for:) open settings
(click:) Preferences: Open Settings (JSON)
Add three lines
{
... # any other settings you have already added (remove this line)
"terminal.integrated.shell.windows": "C:\\WINDOWS\\System32\\cmd.exe",
"terminal.integrated.shellArgs.windows": ["/K", "x:\\xxx\\Anaconda3\\Scripts\\activate.bat x:\\xxx\\Anaconda3"],

Under Linux, git cannot be used, prompt sign_and_send_pubkey: signing failed: agent refused operation
Under Linux, Git cannot be used if the server has already added a public key
Git Clone and other functions cannot be used under Linux. Prompt:
sign_and_send_pubkey: signing failed: agent refused operation
In turn (if no public key is added) :
ssh-add
eval $(ssh-agent -s)
Execute (public key has been added) :
eval $(ssh-agent -s)
Eval $(sSH-Agent-s) system runs at startup
Obviously, the above method requires executing eval $(sSH-agent-s) before using Git for the first time. Otherwise, it is not friendly to use an error. We want to avoid the trouble of eval $(ssh-agent-s) once and for all, which is unlikely to be remembered. Therefore, I need to initialize this command when the system boot, help me to execute this command.
Current user (if you prefer “any configuration is for users”)
modify ~/.bashrc, vim ~/.bashrc
add this line (suggested at the end) :
# 启动 ssh-agent，“> .null”是为了解决在终端喊一嗓子的问题（其实就是将它输出到一个.null文件中去了）
eval $(ssh-agent) > .null
All users (recommended)
modify (may need sudo, add it yourself as necessary) /etc/bashrc, vim /etc/bashrc
add this line (it is recommended to add it at the end) :
# 启动 ssh-agent，“> .null”是为了解决在终端喊一嗓子的问题（其实就是将它输出到一个.null文件中去了）
eval $(ssh-agent) > .null

2, use vscode editor, install live – server plug-in, as shown in figure method is used to open the HTML file, will be forced to make it under the same server. 
mysql Error: Failed to open file “file_name” error 2/error 22
The reason is the same: mysql imports SQL according to the relative path query. For example, When I open mysql in the WWW folder, I enter source Form /test.sql to query the file in the WWW folder.
Solution: Simple, use CMD to enter the folder where SQL files exist, then open mysql, and then import SQL files

Problem
When importing an SSL certificate to Clearwell’s keystore, an error is encountered.
Error Message
keytool error: java.lang.Exception: Failed to establish chain from reply
Cause
Root and/or Intermediate certificates have not been imported order.
I checked that I commented out the original step and did not execute it
That is, import the self-signed certificate (that is, my root certificate) information into the server secret key library
Modify the following, perform this step first, then perform normal.
Summary: The order in which certificates are imported into the secret key library is important, and if there is a root certificate or a multi-level certificate authority, they must be imported level by level from top to bottom.
