Request #21522 has been accepted by yan12125 [1]: Besides what the last packager said - this is no longer a -git version, I deleted this package for another reason: the package in community is called nextcloud-client, and nextcloud-desktop on AUR was deleted [1]. Before there is another consensus that the community package should be renamed as nextcloud-desktop, I prefer the git package called nextcloud-client-git.
