Narrative:
On the initial climb out; we noticed very limited air out of the flight deck gaspers. Shortly after; the flight attendant called and said there was no air coming out of the gaspers in the cabin. We then came to the conclusion that the left pack had been over pressurized. We then proceeded with the QRH procedure and the QRH had us reset the left pack. When we did turn the left pack off and closed the left 10TH stage valve; the right pack worked normally so we requested FL250 as a final. About ten minutes later we got a right pack hi temperature caution message and I noticed cabin pressure raising rapidly about 1400 FPM. We proceeded to don our O2 (oxygen) mask; initiated an emergency descent; and [requested priority handling]. We than diverted to ZZZ.
