Shotwell from Yorba’s daily builds PPA cyrrently depends on “libgee-0.8-2 (>=0.8.3) but it is not installable” on Precise. Fundamentally, this is caused by Yorba (by decision) moving to libgee 0.8 but not packaging a 0.8-series libgee to go along with daily builds of Shotwell.
But libgee 0.8 for Precise is available from the Vala Team PPA, so enabling that PPA allows for the daily shotwell build to install once more.
Additionally, I’m using the PPA downprioritizing trick so that rest of the Vala PPA contents don’t override stuff from official repositories.:
