I was trying to install pycharm on ubuntu bionic beaver(18.04).
I tried the following commands:
sudo sh -c 'echo "deb http://archive.getdeb.net/ubuntu $(lsb_release -sc)-getdeb apps" >> /etc/apt/sources.list.d/getdeb.list' wget -q -O - http://archive.getdeb.net/getdeb-archive.key | sudo apt-key add - sudo apt update
But apt update shows the following:
Hit:1 http://archive.canonical.com/ubuntu bionic InRelease Hit:2 http://in.archive.ubuntu.com/ubuntu bionic InRelease Ign:3 http://screenshots.getdeb.net bionic-getdeb InRelease Err:4 http://screenshots.getdeb.net bionic-getdeb Release 404 Not Found [IP: 184.108.40.206 80] Reading package lists... Done N: Ignoring file 'getdeb.list.bck' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension E: The repository 'http://archive.getdeb.net/ubuntu bionic-getdeb Release' does not have a Release file. N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details.
I tried many on-line solutions like changing server from main to India and vice versa.But not able to correct the problem. Also the link http://archive.getdeb.net/ubuntu gives 404 error.
