Hello.

I'm having a little confusion.
I installed mail.ru cloud via dpkg.

Package: mail.ru-cloud
Status: install ok installed

Maintainer: Mail.Ru Group <[email protected]>
Architecture: amd64
Version: 15.06.0110
Depends: libc6, libx11-6, libxmu6, libqt5widgets5, libqt5x11extras5

Now I'm trying to start the program from the menu, but nothing happens.
I think to run from the terminal, but I do not understand where it was installed.
After all, you can find out the path to the executable file through whereis.
It just whereis mail.ru-clouddoesn't work.
Can you explain what's going on?
Thanks in advance.

Try installing dependencies:
Or reinstall via apt:

echo "deb https://linuxdesktopcloud.mail.ru/deb default free" | sudo tee /etc/apt/sources.list.d/mail.ru-cloud.list
wget -q https://linuxdesktopcloud.mail.ru/mail.ru-cloud.gpg -O- | sudo apt-key add -
sudo apt-get update
sudo apt-get install mail.ru-cloud
