Also had this problem with after an upgrade from Xubuntu 14.10 to 15.05 (xubuntu was installed on top of ubuntu server without recommends if that helps)
Following kgoeser advice I used `sudo apt-get build-dep gitg` to generate a list of missing build dependences: The following NEW packages will be installed: autopoint dh-autoreconf gir1.2-atspi-2.0 gir1.2-gconf-2.0 gir1.2-gdesktopenums-3.0 gir1.2-gee-0.8 gir1.2-git2-glib-1.0 gir1.2-gtksource-3.0 gir1.2-gtkspell3-3.0 gir1.2-javascriptcoregtk-4.0 gir1.2-json-1.0 gir1.2-peas-1.0 gir1.2-secret-1 gir1.2-webkit2-4.0 gnome-common gobject-introspection gsettings-desktop-schemas-dev intltool libatk-bridge2.0-dev libatspi2.0-dev libenchant-dev libgconf2-dev libgcrypt20-dev libgee-0.8-dev libgirepository1.0-dev libgit2-dev libgit2-glib-1.0-dev libgpg-error-dev libgtk-3-dev libgtksourceview-3.0-dev libgtkspell3-3-dev libhttp-parser-dev libjavascriptcoregtk-4.0-dev libjson-glib-dev libpeas-dev libsecret-1-dev libsoup2.4-dev libssh2-1-dev libvala-0.26-0 libwebkit2gtk-4.0-dev libxtst-dev valac valac-0.26 valac-0.26-vapi x11proto-record-dev I don’t like installing unnecessary stuff so I cancelled that and took a punt that I was only missing `gir1.2-peas-1.0`. After a: sudo apt-get install gir1.2-peas-1.0 gitg was all working without errors :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1446746 Title: git not showing commit summary on 15.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gitg/+bug/1446746/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
