Dear Sir,

I removed opam & deleted my .opam folder, and re-installed it , this time version 1.2.2. This time all the opam commands worked without sudo and looks like the installation was right! The last two lines for opam install mirage say "installed mirage.2.6.1

Done."

opam config report Â outputs:

# OPAM config report

# opam-version Â Â1.2.2Â

# self-upgrade Â Âno

# os Â Â Â Â Â Â Âlinux

# external-solver aspcud $in $out $criteria

# criteria Â Â Â Â-removed,-notuptodate,-changed

# jobs Â Â Â Â Â Â4

# repositories Â Â1* (http)

# pinned Â Â Â Â Â0

# current-switch Â4.01.0

# last-update Â Â 2015-09-24 21:01

but mirage --help still doesn't seem to work. Returns ' The program 'mirage' is currently not installed. You can install it by typing:

sudo apt-get install mirage'

Sincerely,

Lasya VÂ

From the screen log you attached I see a lot of errors related to using OPAM 1.1.1. The current version of OPAM is 1.2.2, I believe.Â

How did you install OPAM?

You mention that it seems to be working so could you tell us what the output of the following is:
opam config report

Also, you shouldn't need to use sudo at any point with OPAM.Â

Best wishes,
Amir

Dear Sir,Â

I have tried as per your suggestion but it still doesn't seem to be working. After this, Even though the installation process says "you need not be the root user" I sudo-ed most commands and it seemed to be working, installation seems to be successful from the prompts. (However, typing 'mirage --help' doesn't work yet, says install mirage thought apt-get ). Can I proceed? Or am I doing something wrong?

Sincerely,
Lasya V

Probably a `ulimit` setting, eg.,
http://askubuntu.com/questions/181215/too-many-open-files-how-to-find-the-culprit.

Try `ulimit -a` to see what current limits are, and then something
like `ulimit -n 5000` (or a number bigger than the current limit
anyway) to get around this.

ISTR this was an issue recently with alcotest specifically -- @samoht,
was there a proper fix intended for this at some point? (Or is it
really just a very low default ulimit setting on Ubuntu?)
