Thank you for your help.
If you run $sudo apt update on the Debian10 bash shell, you will get an error and I want to resolve it.
Below is the terminal message.
$sudo apt update

Also, I deleted the Ubuntu repository and wrote /etc/apt/sources.list as below, but I still get an error.The following is a description after deleting the Ubuntu repository in /etc/apt/sources.list.
By the way, the reason I added Ubuntu repository is because I wanted to install fingerprint-gui.

I would like to resolve the above error.I look forward to your kind cooperation.
linux bash debian apt
Once you have removed /etc/apt/sources.list.d/fingerprint-ubuntu-fingerprint-gui-local.list,
$sudo apt update no longer produces errors.
Supplement
/etc/apt/sources.list.d/ Files located below contain information about the APT repository, but these files are usually added and deleted using the add-apt-repository command.
For this fingerprint-gui package, the Fingerprint GUI installation should look like the following (run with root privileges):
##Added
$ sudo add-apt-repositoryppa —fingerprint/fingerprint-gui
## Deleted
$ sudo add-apt-repository-rppa —fingerprint/fingerprint-gui
I wrote "delete", but actually all the contents of the file (fingerprint-ubuntu-fingerprint-gui-local.list) are deleted and the file itself remains (so-called truncate).
