Hi, I need to install a software called QCMA but I simply cannot even though I directly follow the instructions on the website. When I attempt to install the deb package, I get "Error: Dependency is not satisfiable: libvitamtp5 (>= 2.5.5)". I still cannot install it even I follow the second path ("Add repository and install manually"). When I run the command Code: sudo sh -c "echo 'deb http://download.opensuse.org/repositories/home:/codestation/xUbuntu_18.04/ /' > /etc/apt/sources.list.d/home:codestation.list" , I get no feedback. After that, I run the following lines: Code: sudo apt-get update , Code: sudo apt-get install qcma . This time, I encounter this message: . I'd really use some help, Thank you.
