Q:

How can i install perl 5.10.1 in ubuntu 18.04 LTS?

I am not able to install Perl 5.10.1 in ubuntu 18.04. I am trying to install it via perlbrew but I am getting some error.
perlbrew install perl-5.10.1

apt-get install perlbrew
perlbrew init
perlbrew install perl-5.10.1
perlbrew use perl-5.10.1

I have to downgrade the Perl version since I am in need of these for my applications backend

A:

If you update the patchperl component of your perlbrew to the latest version, it should work. See this issue for more information. Try this:
$ perlbrew install-patchperl  # <-- install latest version of patchperl
$ perlbrew install perl-5.10.1
