Alien fails to create deb if directory already exists

[ndefontenay]

1) alien -i any-rpm-file.rpm
2) ctrl+ c to cancel (for example: oh no! I wanted to use --to-deb instead)
3) alien -i any-rpm-file.rmp
4) mkdir: cannot create directory ‘oracle-instantclient12.1-basic-12.1.0.1.0’: File exists

Files affected:
/usr/share/perl5/Alien/Package.pm line 257.
/usr/share/perl5/Alien/Package/Deb.pm line 299

Solution:

Replace mkdir with mkdir -p

 -p, --parents
              no error if existing, make parent directories as needed

Status changed to 'Confirmed' because the bug affects multiple users.

Changing to `mkdir -p` won't help if files were already created.
To fix this issue, insert this line before `mkdir`:
 $this->do("rm -rf $workdir");
