How to solve the problem that Linux cannot change the group affiliation

In a Linux system, only the owner and superuser of a file or directory can change its group. Try the "chgrp groupname filename" command to change the group, where "groupname" is the name of the new group you want to change to. , "filename" is the name of the file or directory whose group you want to change.

The operating system of this tutorial: Linux5.18.14 system, Dell G3 computer.

In Linux systems, you can use the `chgrp` command to change the group ownership of a file or directory. If you cannot change the group ownership of a file or directory, first make sure you have permission to do so. Only the owner of a file or directory and the superuser (root) can change its group.

If you are the owner of the file or directory, you can try the following command to change the group:

```bash
chgrp groupname filename
```

where `groupname` is the name of the new group you want to change to, `filename` is the name of the file or directory whose group you want to change.

If this command fails to execute, it may be because the system administrator has given "Sticky Bit" permissions on the specific directory, that is, the t permission bit is set to 1, and changing group permissions will be prohibited.

In addition, the following problems may occur that prevent you from changing the ownership group:

• There is not enough disk space to update the metadata of the file or directory.

• The file or directory is locked or is being used by another process.

• Disk damage or failure may affect change operations.

Details need to be analyzed according to the specific situation. You can use the `ls -l` or `stat` command to view the current owner, group, ownership and permissions of the file or directory. to help diagnose the cause of the change error.
