Unable to locate package hisat2″

Dear all,

I need to install HISAT2 aligner in my study. My Linux version is 16.04 (Xenial Xerus). So I used the below command :

sudo apt-get install -y hisat2

but I got the below message:

"E: Unable to locate package hisat2"

I installed BWA aligner with that command but I couldn’t install HISAT2. should I install it from the source?

I appreciate it if anybody shares his/her comment and experience with me.

Best Regards,
Mohammad
