I'm trying to install a bunch of packages, but the install script was made for Ubuntu 18.04. I have a few that I'm having trouble with in 20.04. Can someone tell me what are the equivalent versions in Ubuntu 20.04? Thanks.

Error message:

Package libfluidsynth1 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Unable to locate package gudev-1.0
E: Unable to locate package libusb-1.0.0-dev
E: Package 'libfluidsynth1' has no installation candidate
E: Unable to locate package libnettle6
E: Unable to locate package libopenexr22

Edit: I'm also having trouble with libgfortran3.

  • Tip: The devscripts package contains a very handy tool called rmadison that will answer most of these for you. – user535733 Apr 25 at 22:01

libfluidsynth1 Real-time MIDI software synthesizer has been upgraded to libfluidsynth2 in Ubuntu 20.04 and later. To install it open the terminal and type:

sudo apt update  
sudo apt install libfluidsynth2

To install libgfortran3 in 18.04 type:

sudo apt install libgfortran3
