The INSTALL.pl script assumes sudo is installed in the system, and warns "If this step fails... run this script again as superuser". If sudo is not installed, the script does not install anything, and prints the success message. Running the script as root does not actually do anything.

From a Docker container running ubuntu:bionic (ie: docker run -ti --rm ubuntu:bionic bash):

# apt-get update && apt-get -y install bioperl gcc git libbz2-dev liblzma-dev libmodule-build-perl make wget zlib1g-dev
# id
uid=0(root) gid=0(root) groups=0(root)
# cat /etc/issue

# cd /opt ; wget https://github.com/Ensembl/Bio-DB-HTS/archive/2.11.tar.gz ; tar -xzf 2.11.tar.gz ; cd Bio-DB-HTS-2.11; ./INSTALL.pl 
/opt/Bio-DB-HTS-2.11

# ls /usr/local/lib/x86_64-linux-gnu/perl/5.26.1/Bio/DB/HTS/
ls: cannot access '/usr/local/lib/x86_64-linux-gnu/perl/5.26.1/Bio/DB/HTS/': No such file or directory

Behaviour when sudo is installed. Note that I am still root, so using sudo here is redundant.

# apt-get -y install sudo
# ./INSTALL.pl
