[C++ Lib][Ubuntu 20.04] libarrow-dev package not found

[fotiskoun]

Hello,

I am trying to install the C++ headers for arrow and parquet.
For this reason I follow the instructions from this page https://arrow.apache.org/install/
I update, install the certificates and wget, get the deb file, install it and update again.
Everything works great up to here, I can see the arrow-source installed in my system:

apache-arrow-apt-source/now 9.0.0-1 all [installed,local]

Although, when I try running:
sudo apt install -y -V libarrow-dev
I get an Error: Unable to locate package libarrow-dev

I have tried uninstalling and reinstalling or adding keys but it didn't seem to work.

I am working on C++ and I want to include the arrow and parquet headers.
Do you have any suggestions?

Thank you

There was an issue with my sources list, so my system could not correctly install in ubuntu focal the apache-arrow-apt-source.
After updating my sources by adding the following file sudo nano /etc/apt/sources.list.d/apache-arrow.sources with these contents

Types: deb deb-src
URIs: https://apache.jfrog.io/artifactory/arrow/ubuntu/
Suites: focal
Components: main
Signed-By: /usr/share/keyrings/apache-arrow-apt-source.gpg

I run apt get update and I installed again apache-arrow-apt-source, as well as the libarrow-dev and libparquet-dev without any more issues
