Huge list incoming :) Following packages are out of date and orphaned and couldn't be revived, as their source is dead, or better PKGBuilds are available. ------ https://aur.archlinux.org/packages/xspice/ Should be merged with https://aur.archlinux.org/packages/xf86-video-qxl Both are the same ------ https://aur.archlinux.org/packages/synce-gnomevfs superceeded by https://aur.archlinux.org/packages/synce-gvfs ------ https://aur.archlinux.org/packages/wbar-patched/ patches gone ------ https://aur.archlinux.org/packages/hawaii-login-manager-git/ Merged with something else https://groups.google.com/forum/#!topic/sddm-devel/g3kGNWI0A3A ------ https://aur.archlinux.org/packages/meliae-dust/ Downloadlink is dead ------ https://aur.archlinux.org/packages/nimbus/ Better named and maintained package is https://aur.archlinux.org/packages/gtk-engine-nimbus/ ------ https://aur.archlinux.org/packages/ob-pippe-menu/ Seems to be gone ------ https://aur.archlinux.org/packages/obmenugen-bin-fix/ https://aur.archlinux.org/packages/obmenugen/ Changes from the first went into the latter ------ https://aur.archlinux.org/packages/obmenugen-bin/ https://aur.archlinux.org/packages/obmenugen/ Developer suggested the use of the latter. ------ https://aur.archlinux.org/packages/pymouse/ & is replaced by https://aur.archlinux.org/packages/python2-pyuserinput-git/ pymouse got merged into pyuserinput. And versioned pymouse was deprecated in favor for the git version. But the git version https://aur.archlinux.org/packages/pymouse-git has a maintainer! Although last update was 2011-11-04 ------ https://aur.archlinux.org/packages/dpkg-ubuntu/ Source link not available. Long time ood ------ https://aur.archlinux.org/packages/ntfs-3g-fuse-internal/ should propably merged into https://aur.archlinux.org/packages/ntfs-3g-fuse I go along with the commenter that the packages are similar (internal flag) and the latter is better maintained ------ https://aur.archlinux.org/packages/python-grin/ should be merged into https://aur.archlinux.org/packages/python2-grin/ Grin seems to support only python2 (Segfaults with python3) On a sidenote. There is also another package https://aur.archlinux.org/packages/grin/ ------ https://aur.archlinux.org/packages/programmer-dvorak-console-map/ should be merged into https://aur.archlinux.org/packages/programmers-dvorak It's more up to date and maintained ------ https://aur.archlinux.org/packages/qemu-diskp/ Source and page dead. No alternative found ------ https://aur.archlinux.org/packages/englab-cimg/ Superceeded by https://aur.archlinux.org/packages/libenglab-cimg ------ https://aur.archlinux.org/packages/englab-plot/ Superceeded by https://aur.archlinux.org/packages/libenglab-plot ------ https://aur.archlinux.org/packages/englab-matrix/ Replaced and not used ------ https://aur.archlinux.org/packages/englab-special_functions/ Not used ------ https://aur.archlinux.org/packages/khanacademy/ Deprecated and replaced by youtube-viewer ------ https://aur.archlinux.org/packages/needles-git/ Repo gone and I couldn't find a fork. ------ https://aur.archlinux.org/packages/octave-suitesparse/ Octave from [extra] uses suitesparse ------ https://aur.archlinux.org/packages/omnetpp4/ should be merged into https://aur.archlinux.org/packages/omnetpp/ It's more maintained and up-to-date ____________ And here some packages where I'm not sure if they can be removed or not: ------ https://aur.archlinux.org/packages/xf86-video-ati-6.14.2/ Orphaned and ood ------ https://aur.archlinux.org/packages/pacman.manfr/ Orphaned and ood ------ https://aur.archlinux.org/packages/rmlint/ Dunno about that. -git is more active and due to missing tags/releases this cannot be updated. IIRC the download section on github was deprecated in that case ------ https://aur.archlinux.org/packages/quick-boot/ Upstream is gone, so is the wiki. Package may work, but without a docu it seems to be risky. ------ https://aur.archlinux.org/packages/aeskulap/ https://aur.archlinux.org/packages/aeskulap-dcmtkcompat/ The aeskulap package seems to conflict dcmtk and dreieck made a new package to avoid this. As this package is more maintained than the other, they should propably be merged. But the name from the first would be better. ------ https://aur.archlinux.org/packages/grass-svn/ https://aur.archlinux.org/packages/grass7-svn The first has the better name, but the latter is maintained and up to date ____________ Packages that should be merged/removed, but not possible: ------ https://aur.archlinux.org/packages/coin-utils/ https://aur.archlinux.org/packages/coin-or-utils/ Both packages are the same. Though the later was more up-to-date in the past. I suppose the first wasn't updated and someone uploaded the second. In case of naming, there should only exist one of those and more packages are uploaded as coin-*. I wrote a comment and suggested a change. ------ https://aur.archlinux.org/packages/coin-clp/ https://aur.archlinux.org/packages/coin-or-clp/ Same story like the above Best regards Lex
