Fails to install now due to cached dkms, gcc, and gcc-libs being out of date

[kode54]

These packages fail to install from the cached packages folder, due to being obsolete now. It tries to downgrade the kernel and other packages, and outright fails on dkms, gcc, and gcc-libs.

I've had this problem too. Installation failed like this:

I have the same problem. Any solution?

[shatteringlass]

You can check out my fork, in which I tried some dirty hacks in order to bypass the issue. Ultimately the install was not successful, tho.

[yantis]

I am not actively working on this now but if you guys figure it out I can merge it in for everyone else.

What probably needs to happen is not caching the packages anymore as that tends to break it every few months.
