Installation procedure described on https://www.seafile.com/en/help/drive_client_linux/ is inaccurate/does not work with ubuntu
or debian 9 .
deb http://deb.seadrive.org jessie main to /etc/apt/sources.list.d/seafile.list
apt update runs into an error.
There also seems a problem with ubuntu zesty:
error: "The repository 'http://deb.seadrive.org zesty Release' does not have a Release file."
Using the debian jessie release on ubuntu works however. But your HowTo advises to do otherwise. Please fix this.
Thanks in advance!
