I'm trying to install Visual Studio Code, I downloaded deb file and run it. Ubuntu Software was opened but unfortunately when I tried to click install button nothing happened (this is only happening with third-party software). I didn't even get any error message. What can be the problem?
I don't know what the cause was, but I had the same issue. I could install other software, like chess. I couldn't install Atom, though.
I managed to install it from terminal, using command (in case you don't have
gdebi, first type
sudo apt install gdebi-core -y
sudo gdebi code_XX.XXX.XXXXXXX_amd64.deb
where Xs are the version number. You have to run it from directory where you have the deb file.
The simplest way of installing vs code, is to setup a repository
curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.gpg sudo mv microsoft.gpg /etc/apt/trusted.gpg.d/microsoft.gpg sudo sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/vscode stable main" > /etc/apt/sources.list.d/vscode.list'
Then update the package cache and install the package using
sudo apt-get update sudo apt-get install code # or code-insiders
