MarsSeed [1] filed a deletion request for com.taobao.aliclient.qianniu.deepin [2]: Unmaintained, orphaned package, last updated in 2020. Package source got deleted (404). This package is for Taobao Client v7.22 but current release is v9.0. I don't know if the new version needs Wine or not, but the website advertises it as a "brand new PC client". Also, this seems like a closed-distribution application, available only after subscribing to the provider as a webshop owner. During the last year Deepin has discontinued the distribution of unlicensed third-party binary packages. Whoever wants to use the Taobao client has to legally register with the company to acquire a copy of this software. It's safe to delete since Deepin does not carry this package anymore. Also nothing in AUR depends on it. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/com.taobao.aliclient.qianniu.deepin/
