Describe the issue:
I was downloading Graylog but i wasnt able to download Opensearch. When using wget or curl, i was given 403 forbidden. I am new to Linux and Opensearch. Anyone able to guide?
Well, are you trying to install Opensearch by downloading the deb packages manually or through the apt repository?
It seems like your trying both, but you have to decide for one method.
To install it from the apt repo, simply follow the steps described in the documentation. Maybe start with a fresh Debian install.
The other way is by downloading the package manually. You already have the necessary files in your root users home directoriy. To install the packages simpy run
sudo apt install ./opensearch*.deb -y
inside the root users directory .
The official deb package ist not signed. Therefore this error should not even be possible to occur.
Also your downloadlink does not match the one from the opensearch documentation.
Consider downloading yout package via curl or wget from this link:
