Profile update for gentoo
 

Hi Guys,
I am trying to update my gentoo box profile, of course i read that updating the portage should be done first but my issue is: I fail to update portage, and it's throwing the following error:
"Calculating dependencies... done!

!!! All ebuilds that could satisfy "app-shells/bash-completion" have been masked.
!!! One of the following masked packages is required to complete your request:
- app-shells/bash-completion-1.3 (masked by: EAPI 3)
- app-shells/bash-completion-1.2 (masked by: EAPI 3)

The current version of portage supports EAPI '2'. You must upgrade to a
newer version of portage before EAPI masked packages can be installed."
it's controversial because as I understood : in order to update the portage you have to update the portage first :D.

so I tried this "emerge --nodeps portage" to try the update without paying attention to dependencies, and agin failed and gave me this:
>>> Emerging (1 of 1) sys-apps/portage-2.1.9.42
Traceback (most recent call last):

Please help!

You need to emerge a middle version, which is compatible with eapi3, then you can do the full update. Try this:

Then try updating again.
