I'm trying to install old ruby version on Ubuntu 20.4 by using the RVM by using the below command
$ rvm install "ruby-2.1.6"
Usually I'm got the error
Installing required packages: bison, libgdbm-dev, libncurses5-dev, libyaml-dev, sqlite3 - please wait Error running 'requirements_debian_libs_install bison libgdbm-dev libncurses5-dev libyaml-dev sqlite3'
so, When i'm running
sudo apt-get install bison libgdbm-dev libncurses5-dev libyaml-dev sqlite3
Also I get the error
Reading package lists... Done Building dependency tree
Reading state information... Done Note, selecting 'libncurses-dev' instead of 'libncurses5-dev' Package libyaml-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 'bison' has no installation candidate
E: Package 'libgdbm-dev' has no installation candidate p
E: Package 'libyaml-dev' has no installation candidate

How I can fix this issue?
