MarsSeed [1] filed a deletion request for libappindicator-bzr [2]: Upstream development discontinued since 3 years ago (2020). [a]
Therefore this VCS package is on the exact same commit version, which means it's a duplicate of extra repo's libappindicator-gtk3. [a]: https://code.launchpad.net/libappindicator [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/libappindicator-bzr/
