There can be various reasons why the .bashrc file is not loaded at Ubuntu startup. Here are some possible causes and their solutions:

1. The .bashrc file does not exist or has been accidentally renamed: Check that the .bashrc file exists in the user's home directory and that the file name is correct. If the file has been accidentally renamed, rename it back to .bashrc.

2. The .bashrc file does not have the correct permissions: Check that the .bashrc file has the correct permissions to be executed. Use the command ls -l ~/.bashrc to display the file's permissions and make sure that the current user has read and execute permissions on the file.

3. The .bashrc file contains syntax errors: Check that the .bashrc file does not contain syntax errors. You can use the command bash -n ~/.bashrc to check the file's syntax and detect any errors.

4. The .bashrc file has not been loaded in the Bash configuration file: Check that the .bashrc file has been added to the Bash configuration file (~/.bash_profile or ~/.bash_login). If the Bash configuration file does not exist, create a new file and add the following line:

   bashCopy code

   source ~/.bashrc

   Alternatively, you can add this line to the .profile file in the user's home directory.

5. The Bash configuration file has been modified: Check that the Bash configuration file (~/.bash_profile or ~/.bash_login) does not contain any other instructions that prevent the .bashrc file from being loaded. For example, there might be a line in the configuration file that exits the script without loading the .bashrc file.

In my case it was sufficient to delete .profile in the user's directory.
