Syncthing reports bad version, confusing other clients

[Constantine Evans]

Syncthing (1.1.4~ds1-4) in Eaon results in *other* clients (eg, one running 1.0.1) reporting the error "Not sending symlinks to old client {EAON CLIENT} - please upgrade to v0.14.14 or newer". It appears that it reports its version as "unknown-dev". From the log of the 1.0.1 client:

2019-10-07 06:05:13 Device {DEVICE ID} client is "syncthing unknown-dev" named "{DEVICE NAME}" at {IP ADDRESS}/tcp-server

Status changed to 'Confirmed' because the bug affects multiple users.

Syncthing-GTK is failing to set itself up due to a bad version from Syncthing itself. It reports "Syncthing-GTK needs Syncthing daemon 0.14.50 or newer, but only v0.0 were found."

The daemon was installed as a dependency via Muon and reports:
$ syncthing --version
syncthing unknown-dev "Erbium Earthworm" (go1.12.9 linux-amd64) unknown@unknown 1970-01-01 00:00:00 UTC

Steps:
 * Kubuntu 19.10
 * Install syncthing-gtk via Muon
 * Run syncthing-gtk and try to setup

I hit the same thing in Ubuntu 19.10 with syncthing 1.1.4~ds1-4. I worked around it by downloading the official release from syncthing github (https://github.com/syncthing/syncthing/releases) and replacing the binary /usr/bin/syncthing with it. Not ideal but works.

An alternative workaround that worked for me is to use the upstream PPA: https://apt.syncthing.net/

[Owen (owen-ozone)]

Still present on Focal, Kubuntu 20.04 here, syncthing version reported as "unknown-dev".
This was resulting in the "Not sending symlinks to old client" log messages and symlinks failing.
Fixed by installing 1.6.1 from the ppa above.
