I'm having problems installing .deb packages. I tried to install vscode and chrome and failed.
The error suggests to enter a .deb package, when installing with terminal need run
sudo dpkg -i *.deb and
sudo apt-get install -f.
If you go by command line, there are numerous ways to install the .deb packages but I’ll go with the simplest one. Open a terminal and use the following command:
sudo apt install (path to deb package)
Install gdebi :
sudo apt-get install gdebi
Now, right click on the .deb pckage and select to open it with gdebi.
