Can't install pgAdmin4 in Linux (Debian 12)?

Question

I'm trying to install pgAdmin4 on Debian Bookworm, but I'm encountering a "Hash Sum Mismatch" error during the apt update process. Here are the steps I followed and the error I'm getting:

1. I added the pgAdmin4 repository and key using the following commands:

curl -fsS https://www.pgadmin.org/static/packages_pgadmin_org.pub | sudo gpg --dearmor -o /usr/share/keyrings/packages-pgadmin-org.gpg
sudo sh -c 'echo "deb [signed-by=/usr/share/keyrings/packages-pgadmin-org.gpg] https://ftp.postgresql.org/pub/pgadmin/pgadmin4/apt/$(lsb_release -cs) pgadmin4 main" > /etc/apt/sources.list.d/pgadmin4.list && apt update'

2. When I run sudo apt update, I get the following error:

E: Failed to fetch https://ftp.postgresql.org/pub/pgadmin/pgadmin4/apt/bookworm/dists/pgadmin4/main/binary-amd64/Packages.gz  Hash Sum mismatch

As a result, I cannot install pgAdmin4 using sudo apt install pgadmin4.
