Circular dependencies

YPenguin · Posted: Tue Jan 19, 2016 11:48 am Post subject: Circular dependencies

I have got the following problem (after not updating for about 10 months):

quote:
i7 ~ # emerge --ask 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.

- app-emulation/aranym-0.9.16::gentoo (masked by: package.mask)

end of quote

How would you solve this?
*Backtrack=30 does not solve it
*Masking one package leads to autounmask asking for unmask

Maybe the thread title should be renamed 'slot conflict" and moved to the portage threads?

I would try, for starters:

Unmerging layman and gentoolkit did not change the situation.

It now looks like this:

So it did change in respect to portage but installation is still not possible.

The procedure allowed me to emerge portage. Thanks!
