1. Go to https://insynchq.com/downloads and select Linux and press download
2. Select Repositories and follow the instructions.
You might encounter the following sample error messages if you don’t run the first command in the instructions:
E: Failed to fetch http://apt.insynchq.com/ubuntu/dists/cosmic/InRelease 403 Forbidden
E: The repository 'http://apt.insynchq.com/ubuntu cosmic InRelease' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
http://yum.insynchq.com/centos/7/repodata/repomd.xml: [Errno 14] HTTP Error 403 - Forbidden
If you ran it and the error message still happens, you might need to double-check the file at:
/etc/apt/sources.list.d/insync.list (APT) or
/etc/yum.repos.d/ (YUM). Make sure that the distribution and codename match your current OS.
If any errors persist, shoot us an email at email@example.com and provide all relevant details. :)
