#tahoe-lafs (webchat)

Tahoe-LAFS (Least Authority File System) is an encrypted, secure, distributed (fault-tolerant) file system). It does not require trust between parties in order to keep data safe and secure; the only caveat being involved parties must leave their system's connected to the storage network.

Important
tahoe-lafs was removed from gentoo ebuild repository on 2020-01-04 with [1]

Installation

Kernel

(Optional section. Remove if not applicable.)

KERNEL

Write kernel feature instructions here.

USE flags

There are only a couple USE flags available for Tahoe-LAFS, neither of them incorporate additional functionality. Essentially when more documentation is desired make sure the doc flag is enabled in /etc/portage/package.use.

Emerge

Install Tahoe:

root #emerge --ask net-fs/tahoe-lafs

Configuration

(Needs written...)

Usage

(Needs written...)

Invocation

Tahoe can be invoked via:

user $tahoe

Troubleshooting

Emerge fails

emerge tahoe-lafs fails with a pkg_resources.DistributionNotFound error similar to the following:

CODE Tahoe-LAFS emerge failure

The work around to this problem is to roll back the dev-python/setuptools package to an earlier version. It appears version 12.0.1 which is currently marked as stable on amd64 as an issue determining versioning for Python dependencies. Rolling back to version 7.0 should do the trick:

root #emerge --ask =dev-python/setuptools-7.0

After the new version of dev-python/setuptools is installed proceed with installation process as normal.
