Syncthing needs to be removed more thoroughly from [desktop]
Which package should be removed, and why?
pacman -Ss syncthing still shows the outdated version (along with
syncthing-relaysrv). Furthermore, both
chaser update and the equivalent
ccr -Syu --ccronly completely ignore the CCR version. As a workaround, it's necessary to run
chaser install syncthing or
ccr -S --ccronly syncthing to switch to the CCR version, and again on every update.
Disclaimer: I am the current maintainer of the CCR Syncthing package.
Related: #113 (closed), where an outdated Syncthing was reported and its removed status clarified. It seems that everyone except the repo knows that it's been removed. ;)
