Posix locking issue on first launch of pants

[photoroman]

I recently tried different versions of pants, but couldn't get it to work on the development machine/server I'm using:

With scie-pants version 0.12.5 (latest)

roman@login-0:~/computer_vision$ curl --proto '=https' --tlsv1.2 -fsSL https://static.pantsbuild.org/setup/get-pants.sh > install.sh
roman@login-0:~/computer_vision$ bash install.sh

Installed the pants launcher from https://github.com/pantsbuild/scie-pants/releases/latest/download/scie-pants-linux-x86_64 to /home/roman/.local/bin/pants

Running `pants` in a Pants-enabled repo will use the version of Pants configured for that repo.
In a repo not yet Pants-enabled, it will prompt you to set up Pants for that repo.

Isolates your Pants from the elements.

Please select from the following boot commands:

<default> (when SCIE_BOOT is not set in the environment)  Detects the current Pants installation and launches it.
bootstrap-tools                                           Introspection tools for the Pants bootstrap process.
update                                                    Update scie-pants.

You can select a boot command by setting the SCIE_BOOT environment variable.

With scie-pants version 0.12.3 I get a slightly different error:

Perhaps the issue is related to the fact that ~/.cache/nce resides on a network drive (NFS4) in my setup? File locking does not work reliably on shared filestystems, I believe.

Thanks in advance for your help!
