Check "Notify of new comments" at https://aur.archlinux.org/packages/yaourt/ , so next time you don't need to ask a stupid question about an official unsupported tool anymore, at an AUR unrelated mailing list, since the yaourt comments nowadays are misused as a forum, it's impossible to miss even the slightest issue and workarounds [1]. However, again yaourt isn't out-of-date and there's no need to rebuild it. As Eli already pointed out, you need to rebuild package-query{,-git} [2], to do this download the tarball and use makepkg. [1] zanny commented on 2016-02-29 21:02 New package-query fixes everything, crisis averted. Thank you to all the hardworking volunteers for pushing a release so quickly! Skunnyk commented on 2016-02-29 20:45 Please update to package-query 1.8 (just released: https://aur.archlinux.org/packages/package-query). It should fix all rpc v5 problems. A new yaourt version will follow in a few days. Ralf_Mardorf commented on 2016-02-29 13:08 If something like this happens, I build temporarily from git, but keep the package name without the "-git" extension, instead I add an "r" to the output of git describe. [rocketmouse@archlinux package-query]$ pacman -Q package-query package-query 1.7.r172.g4d856ec-1 An official release update of package-query should replace the temporarily build package. Skunnyk commented on 2016-02-29 12:08 Yes, the "old" aur rpc api is broken since this morning (new api included in aurweb 4.2.0, see https://lists.archlinux.org/pipermail/aur-dev/2016-February/003993.html ) Fortunately, package-query-git already support the new api v5. We need to make an official release of yaourt / package-query to fix theses problems. viq commented on 2016-02-29 09:35 gourdacaptain: pacaur seems to manage fine right now gourdcaptain commented on 2016-02-29 07:06 Similar issue. Does anyone know if this is also applying for other AUR helpers? EDIT: Installing package-query-git fixed the issue for now. josephgbr commented on 2016-02-29 06:13 Me too. It looks like package-query is unable to get package list for some reason. Baemir commented on 2016-02-29 05:37 yay complete breakage zanny commented on 2016-02-29 05:28 Yea I'm not seeing any AUR packages. Fairly sudden, I'm wondering if something on the AUR server is down that yaourt uses. diogobaeder commented on 2016-02-29 05:07 Am I the only one getting "target not found" for any AUR package, with yaourt?
