prompter: I am getting the following error after I install a local .deb file on linux, and I don't know what's causing it. Do you know what the causes and solutions for this error might be? The error is:

"N: Download is performed unsandboxed as root as file '/root/assets/Dungeondraft-1.0.4.7-Linux64.deb' couldn't be accessed by user '_apt'. - pkgAcquire::Run (13: Permission denied)"

assistant: The error message suggests that the download of the .deb file was performed as the root user, which means that the package manager (apt) is unable to access the downloaded file because it is owned by the root user and _apt does not have permission to access it.

To solve this issue, you can change the ownership of the downloaded file to _apt user or move the file to a directory accessible by _apt user.

Here are two possible solutions:

1. Change the ownership of the downloaded file to _apt user:
```bash
sudo chown _apt:_apt /root/assets/Dungeondraft-1.0.4.7-Linux64.deb
```

This will change the ownership of the file to _apt user, which should allow apt to access the file.

2. Move the file to a directory accessible by _apt user:
```bash
sudo mv /root/assets/Dungeondraft-1.0.4.7-Linux64.deb /var/cache/apt/archives/
```

This will move the file to the apt cache directory, which is accessible by _apt user. After moving the file, you can try to install the package again using apt

prompter: How do I install .deb files without sudo?

assistant: The following error appears to occur when _apt user does not have access to the downloaded .deb file.

This could indicate that the folder 
'/root/assets' does not have readable permission for other users. You could try fixing by following methods 
1) Move  Dungeondraft-1.0.4.7-Linux64.deb to a folder that is readable by _apt. You could copy it to /tmp for example, and install from there and it will get rid of that warning.
2) Change the access permissions of the folder you are installing from. To perform so in a linux environment use following commands:
> sudo chmod +r /root/assets

This will grant other users read access.

3) You can try changing ownership of the folder to be owned by '_apt'. To perform so in a linux environment use following commands:
> sudo chown -Rv _apt /root/assets

If the above don't work it could also be a bug within the package manager. Check with the latest bug reports online to see if the running version may have already encountered similar issues.

prompter: Ok, let me check your solution,

prompter: Ok, thank you and sorry for the detour. 
I think it is a user permission problem between the 'sudo' and '_apt' user. Can you explain to me the differences of users permissions in Linux?
