Software-Center crashing bug (Bus error)

Question

My Ubuntu Software Center keeps crashing when I try to run it. What's even weirder is that this is happening on two laptops and across two versions of Ubuntu (14.04 and 16.10). On 14.04 this is the error that comes up:

...$ software-center

I tried various things to fix it (including How can I fix my software center? and Software-center crashes: bug or configuration error?), and even more on my 16.10 machine and in the end I don't recall anything ever working properly. Besides, both times it was happening on fresh installs of ubuntu. Anyone know how to fix this?

was there any significant thing done before this started happening ? — George Udosen, Dec 07 '16 at 19:24

I tried doing what the top answer suggest and it changed nothing. I don't think it's the same problem. Also, I didn't do anything at all to ubuntu or to the software center before this, the computer and installation is brand new. — Marses, Dec 08 '16 at 13:32
If I could ask one more thing, is the last line about it being a Bus error significant in any way? Because my firefox is also crashing and the last line is the same. — Marses, Dec 08 '16 at 13:34
Yes, completely brand new. It's a Spectre x360 13t if that helps. What would the bus be referring to then? And why would it only happen for two programs? — Marses, Dec 08 '16 at 15:02
I upgraded to kernel 4.8.14 and while it could have been something else, the issue seems to have been resolved. — Marses, Dec 11 '16 at 16:24
Glad to hear you have fixed it, guess that was the solution! — George Udosen, Dec 11 '16 at 16:31
