Trying to setup a development environment for opencpn on Ubuntu 20.04 (focal).
I get the following error message:
dave@nuc3:~$ sudo apt-get install build-essential cmake gettext git-core gpsd gpsd-clients libgps-dev wx-common libwxgtk3.0-dev libglu1-mesa-dev libgtk2.0-dev wx3.0-headers libbz2-dev libtinyxml-dev libportaudio2 portaudio19-dev libcurl4-openssl-dev libexpat1-dev libcairo2-dev libarchive-dev liblzma-dev libexif-dev libelf-dev libsqlite3-dev [sudo] password for dave: Reading package lists... Done Building dependency tree Reading state information... Done Note, selecting 'git' instead of 'git-core' Package libwxgtk3.0-dev 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: Package 'libwxgtk3.0-dev' has no installation candidate
Can anyone suggest how I might resolve the missing libwxgtk3.0-dev library?
