I installed Gentoo using CloverOS. Seems like a reasonable thing to do, it was amazingly fast. Comment a few lines in make.conf, emerge --sync && emerge -Dnua world and you're good right? But Clover is a somewhat tweaked gentoo, and I think more relevant: I did this just as things were happening with respect to Python. Always a mess.
So here is my situation now:
| Code: |
bartali /usr/src/linux # equery list portage
* Searching for portage ...
[I--] [??] sys-apps/portage-2.3.89-r1:0
bartali /usr/src/linux # equery list portage -p
* Searching for portage ...
[-P-] [ ] sys-apps/portage-2.3.99-r2:0
[-P-] [ ~] sys-apps/portage-2.3.100:0
[-P-] [ -] sys-apps/portage-9999:0
|
I am force-upgraded from portage 2.3.89 to 2.3.99. Seems like not such a huge jump. BUT when I try to do this I get:
| Code: |
bartali /usr/src/linux # emerge -1pv portage
These are the packages that would be merged, in order:

It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously. If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously. You may want to try a larger value of
the --backtrack option, such as --backtrack=30, in order to see if
that will solve this conflict automatically.
For more information, see MASKED PACKAGES section in the emerge man
page or refer to the Gentoo Handbook.

And so I have multiple slot conflicts. It seems like the system requires python 2.7 and 3.6 while the required new portage requires only python 3.7. Am I understanding this correctly? Is there a way to get to a portage that can update the rest of the system? Or is it "you can't get there from here".
So I'm beginning to believe it was a mistake to try to install this way in the middle of the dance of the Pythons, and that I should install again from scratch with a minimal install cd. oops! That doesn't recognize my NVME drive, a whole different set of messes.
Is there no way forward for this system?

Any help would be gratefully accepted.

Was that old portage verions from a freshly downloaded snapshot? Which snapshot did you use? |

I got past that problem by adding:
| Code: |
*/* PYTHON_TARGETS: -python3_7 python3_6
*/* PYTHON_SINGLE_TARGET: -* python3_6
|
to /etc/portage/package.use as suggested in the news item. Portage could then update itself.
Now on to the next set of problems.
thanks!
Jon. |
