Can't install normally, via opam, nor debian stretch on GCP

[BigTimeStats]

I tried the regular install method and get "no valid OpenPGP data found."

I tried to install via opam and then get error: "-bash: google-drive-ocamlfuse: command not found"

xxx@instance-1:~$ opam init
OPAM has already been initialized.
In normal operation, OPAM only alters files within ~/.opam.

During this initialisation, you can allow OPAM to add information to two
other files for best results. You can also make these additions manually
if you wish.

If you agree, OPAM will modify:

  - ~/.profile (or a file you specify) to set the right environment
    variables and to load the auto-completion scripts for your shell (bash)
    on startup. Specifically, it checks for and appends the following line:

    . /home/xxx/.opam/opam-init/init.sh > /dev/null 2> /dev/null || true

  - ~/.ocamlinit to ensure that non-system installations of `ocamlfind`
    (i.e. those installed by OPAM) will work correctly when running the
    OCaml toplevel. It does this by adding $OCAML_TOPLEVEL_PATH to the list
    of include directories.

If you choose to not configure your system now, you can either configure
OPAM manually (instructions will be displayed) or launch the automatic setup
later by running:

   opam config setup -a

Do you want OPAM to modify ~/.profile and ~/.ocamlinit?
(default is 'no', use 'f' to name a file other than ~/.profile)
    [N/y/f] y

User configuration:
  Generating ~/.ocamlinit.
  Updating ~/.profile.
Global configuration:
  ~/.opam/opam-init/init.sh is already up-to-date.
  ~/.opam/opam-init/init.zsh is already up-to-date.
  ~/.opam/opam-init/init.csh is already up-to-date.
  ~/.opam/opam-init/init.fish is already up-to-date.

Unfortunately your opam version is too old. You should install opam 2 (http://opam.ocaml.org/doc/Install.html). And after that you should install an updated OCaml compiler (e.g.: opam switch create 4.08.0).

[BigTimeStats]

Thanks for taking a look @astrada. I was able to install opam 2:

xxx@instance-1:~$ opam --version
2.0.5

I'm getting errors when running opam switch create 4.08.0

The 'bwrap' command was not found. Install 'bubblewrap' on your system, or disable sandboxing in ~/.opam/config at your own risk.

You need to install package bubblewrap.

[BigTimeStats]

@astrada Thanks, gave installing bubblewrap a try and failed... getting configure: error: *** POSIX caps headers not found. The errors just keep compounding at this point. Is there any reason why sudo add-apt-repository ppa:alessandro-strada/ppa doesn't work as per the above?

[astrada]

gave installing bubblewrap a try and failed

You should install bubblewrap with apt.

why sudo add-apt-repository ppa:alessandro-strada/ppa doesn't work as per the above?

Because the ppa is for Ubuntu distros.

Thanks, going to just re-roll to ubuntu. Any instance/version you recommend on GCP?

[astrada]

I think Ubuntu 18.04 LTS is the safest choice.

Awesome thanks for the help.. install worked on Ubuntu 18.04
