I am running Linux on Windows (Ubuntu) to install a bioinformatics software (MEME Suite - Installation Guide). Please bear in mind I do not have much experience using Linux.
I am following the instructions and I need to install some Perl modules.
I was able to install all the required ones via sudo cpan except Sys::Info.
When I run sudo cpan Sys::Info this is the first error I find on the log:
Running install for module 'Sys::Info'
Checksum for
/root/.cpan/sources/authors/id/B/BU/BURAK/Sys-Info-0.7811.tar.gz ok
'YAML' not installed, will not store persistent state
Configuring B/BU/BURAK/Sys-Info-0.7811.tar.gz with Makefile.PL
Checking if your kit is complete...
Looks good
Warning: prerequisite Sys::Info::Driver::Linux 0.78 not found.
Then, when it tries to install Sys::Info::Driver::Linux, I get the following error:

I can not open file /proc/swaps for reading: No such file or directory
at /usr/local/share/perl/5.30.0/Test/Sys/Info/Driver.pm line 92.
Looks like your test exited with 2 just after 65.
Probably it has something to do with my Linux on Windows installation, but I am completely lost. I can provide the full log if needed.
EDIT: I found the OS.pm file and the possible error:
# user methods
sub is_root {
return 0 if defined &Sys::Info::EMULATE;
my $name = login_name();
my $id = POSIX::geteuid();
my $gid = POSIX::getegid();
return 0 if $@;
return 0 if ! defined $id || ! defined $gid;
return $id == 0 && $gid == 0 && $name eq 'root';
}
Any advice would be much appreciated!
