5 git owner exception
An exception prompt appears when committing:
Check the log as follows:
(fastapi-py310) PS D:\projects\py\python-tutorial> git log
fatal: detected dubious ownership in repository at 'D:/projects/py/python-tutorial'
' D:/projects/py/python-tutorial' is owned by:
'S-1-5-21-2994888592-1342716116-403010676-500'
but the current user is:
'S-1-5-21-2994888592-1342716116 -403010676-1001'
To add an exception for this directory, call:
git config --global --add safe.directory D:/projects/py/python-tutorial
(fastapi-py310) PS D:\projects\py\python-tutorial>
5.1 Reasons
The notebook cannot be connected to the Internet, reinstall win11,
change the operating system user, and the git project does not change the user, resulting in inconsistent users.
5.2 Scheme
The user who modifies the git project folder.
Find the project folder, in order: right click -> Properties -> Security -> Advanced -> Change, etc. as shown in the figure below.
Note: The account I configured is a personal account, not admin, which varies depending on the current user of the system.
4 Common Docker users have no permissions
Ordinary users execute the docker command prompt information:
docker images
docker ps -a
docker: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post “http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/create?name=redis-module”: dial unix /var/run/docker.sock: connect: permission denied.
4.1 Reasons
The current user is not in the Docker user group.
4.2 Scheme
The current user is added to the user group. Since it is only a virtual machine operated by individuals, the current user is added to the docker user group.
$USER gets the current user, if it is another user use $your-username.
# 添加用户组
sudo groupadd docker
# 主机用户添加到docker用户组
sudo gpasswd -a $USER docker
# 更新用户组
newgrp docker
3 Ubuntu22.04 installs docker abnormally
Ubuntu22.04 installed Docker with the following exception,
because apt-get was used when installing the software last time, and the installation was interrupted midway.
sudo apt install docker.io
The exception information is as follows:
Waiting for cache lock: Could not get lock /var/lib/dpkg/lock-frontend. It is hWaiting for cache lock: Could not get lock /var/lib/dpkg/lock-frontend. It is held by process 1749 (unattended-upgr)
tried to delete the file: /var/lib/dpkg/lock-frontend
installed again, the exception information is as follows:
E: Could not get lock /var/cache/apt/archives/lock. It is held by process 1749 (unattended-upgr)
N: Be aware that removing the lock file is not a solution and may break your system.
E: Unable to lock directory /var/cache/apt/archives/
Delete related files again: /var/cache/apt/archives/lock
to install normally.
3.1 Reasons
The file is occupied by an interrupted thread/service, has not been freed, and cannot be read or written.
3.2 Scheme
delete locked files
sudo rm /var/lib/dpkg/lock-frontend
sudo rm /var/cache/apt/archives/lock

Starting SpringBoot is to exclude this class.
