yupi [1] filed a deletion request for opensc-esteid [2]: This was a temporary patched version of opensc 0.17, which enabled signing for a subset of Estonian id-cards. It is superseded by opensc 0.18+, which contains the needed patches. [1] https://aur.archlinux.org/account/yupi/ [2] https://aur.archlinux.org/pkgbase/opensc-esteid/
