Errors during install on Xenial, missing ppa package

[libremente]

Hi, I am trying to follow this guide in order to install and test the module on a ficus.1 devstack but I am encountering some errors. First of all during the install-sys-requirements I get:

W: http://packages.elasticsearch.org/elasticsearch/0.90/debian/dists/stable/Release.gpg: Signature by key 46095ACC8548582C1A2699A9D27D666CD88E42B4 uses weak digest algorithm (SHA1)
W: http://downloads-distro.mongodb.org/repo/ubuntu-upstart/dists/dist/Release.gpg: Signature by key 492EAFE8CD016A07919F1D2B9ECBEC467F0CEB10 uses weak digest algorithm (SHA1)
sudo xargs -a apt-packages.txt apt-get install -qq --fix-missing
E: Unable to locate package libblas3gf
E: Unable to locate package liblapack3gf

and it seems [1] [2] that those packages do not exist in Xenial. Anyway trying to comment them out from the apt-packages.txt I still get problems during the install because it is trying to fetch node.js from this repo:

http://ppa.launchpad.net/chris-lea/node.js/ubuntu/dists/xenial/main/binary-amd64/Packages

which does not exist.

Am I missing something? Thanks

@libremente how did you manage to solve this? Because facing the exact same error with gingo box.

@hasnain-naveed unfortunately I couldn't solve it. Maybe you can try to find the repositories containing those packages and manually add them (but it's not a good practice). Hopefully someone else can help you better.
