Apology is this sound stupid.
I have a previous installation of CDH5.5.1 which I have uninstalled and wanted to do a new fresh installation using a local repository.
I've created a local repository which can be accessed through browser. To do that I've created a file named /custom-repo.list inside /etc/apt/sources.list.d/ with the following content in it ..
deb [arch=amd64] http://xxx.xx.xx.xxx/cm5.5.1 trusty-cm5.5.1 contrib
deb-src [arch=amd64] http://xxx.xx.xx.xxx/cm5.5.1 trusty-cm5.5.1 contrib
after that when I do apt-get update it shows a error like:
W: GPG error: http://xxx.xx.xx.xxx trusty-cm5.5.1 InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 327574EE02A818DD
I tried running
$ apt-get clean
$ rm -rf /var/cache/apt/*
$ rm -rf /var/lib/apt/lists/*
But I am keep getting the same error as above, commenting the repository entry from custom-repo.list seems to resolve this. But as soon as I bring that back the same error is thorwn.
What m I doing wromg here? could this happen due to improper uninstallation ?
I am stuck at this and not able to move forward with the installation. any help would be highly appreciated
