We test each SpiderOak ONE release against the latest 64 bit stable versions of Ubuntu, Ubuntu LTS, CentOS, and Fedora. We additionally try to also test on the latest 32 bit versions of all of these, plus the latest 64 bit versions of Debian stable and OpenSUSE.
ONE is available as an RPM, a DEB, and as a tarball for manual installation. We do not currently distribute in other packages such as Snap, AppImage, or Docker containers. Do let us know if you would find a particular package useful so that we can gauge interest.
We regularly receive reports of SpiderOak running fine on Debian testing, Red Hat Enterprise Linux, Mint, Mageia, and other popular distributions, but we do not formally test on them and we cannot offer advanced troubleshooting for them. Likewise we are unable to officially support rolling release distributions, beta releases, or unstable or testing releases.
The builders for each package is on a standalone platform, so supporting earlier releases is possible if the builder platform can meet the dependencies. If you get dependency errors when installing, it is because one of these components in the system are too old. A common one is glibc.
If you aren't sure if SpiderOak ONE will work on your preferred distribution and release, we encourage you to give it a try at no cost with a 250 GB 21 day trial.
