 |

I have a machine that I am trying to upgrade and am having a problem...
| Code: |
# emerge -pv portage
These are the packages that I would merge, in order:
Calculating dependencies ...done!
[blocks B ] <dev-lang/python-2.3.6-r2 (is blocking app-admin/python-updater-0.2)

recalculate dependencies, and complete the merge.
You may avoid the remerging of packages by updating portage on its own.

basically I need python-2.4.4-r4 on my system before portage can merge anything that lists portage-updater as a dependency, and python-2.4.4-r4 lists python-updater as a dependency. I submitted this as a bug but was told it was not a bug and was forwarded here and that the block is there for a reason. This makes me nervous trying to get around it since if it's there for a reason it seems like getting around it would be trivial. Not to mention we are talking about python here which can hose portage if I make a wrong decision.
My current idea is to install everything up to python-2.4.4-r4 (which I've already been doing, with sandbox the only thing remaining) and then install 2.4.4-r4 with --nodeps. Then install python-updater.
My question is: is this safe to do?
It looks like 2.3 and 2.4 will coexist just fine but that the python-updater can not merge if the highest version installed is less than 2.3.6-r2. I have already tried several combinations of safe options and various packages and utilities to get around this problem, so no need to recommend something like emerge =dev-lang/python-2.4.4-r4 or emerge -u python, etc, unless you know it will work.
I suspect the underlying problem is that this machine wasn't touched for 1.5 years and I think in that time updates to portage handled this situation just fine but at some point people who didn't already have 2.4 installed and an old version of portage wound up blocked. |

|
|
hi
I had the same problem, just found your post. Turns out I have 2 versions of python, a 2.3* and a 2.4*
the issue is that the 2.3* version is too low. find this out by "equery list python"
in order to upgrade the lower python I set this in my /etc/portage/package.keywords
| Code: | | =dev-lang/python-2.3.6-r2 ~x86 |
I then executed an upgrade like this:
| Code: | | emerge -av =dev-lang/python-2.3.6-r2 |
This upgrade effectively pulled in the prerequisites, including python-updater. I can now emerge system as I intended. Should work for you as well.
good luck
Leo |

Hi Leo, thanks for the reply.
Unfortunately that doesn't work. I had somewhat tried that before with USE="~x86" emerge =dev-lang/python-2.3.6-r2
When I try what you specified above, I get this:
| Code: | # cat /etc/portage/package.keywords
=dev-lang/python-2.3.6-r2 ~x86
|
| Code: | # emerge -av =dev-lang/python-2.3.6-r2
These are the packages that I would merge, in order:
Calculating dependencies ...done!

[/code]I should also point out this which seems like a bug:
| Code: |
# USE="~x86" emerge -pv =dev-lang/python-2.3.6-r2
These are the packages that I would merge, in order:
Calculating dependencies
!!! All ebuilds that could satisfy "=dev-lang/python-2.3.6-r2" have been masked.
!!! One of the following masked packages is required to complete your request:
- dev-lang/python-2.3.6-r2 (masked by: ~x86 keyword)
|
and...
| Code: |
# ACCEPT_KEYWORDS="~x86" emerge -pv =dev-lang/python-2.3.6-r2
These are the packages that I would merge, in order:
Calculating dependencies ...done!

| Install python-updater with --nodeps, then install >=python-2.4, then install >=portage-2.1.2, then run python-updater, then update or remove python-2.3 (the order is very important) |

Thanks Genone, I'm attempting that right now.
It's similar to what I wanted to try except I was going to --nodeps 2.4.4-r2. I'm glad you gave me the right order.
Is this a bug then? Seems like python-updater should block on <2.3.5-r2 not <2.3.6-r2
Also, if you have time, could you explain how you were able to determine the proper order to install these? |

No, the blocker is correct (<python-2.3.6-r2 included the python-updater script directly, later versions split it into a separate package).
| Quote: | | Also, if you have time, could you explain how you were able to determine the proper order to install these? |
The core problem is a circular dependency python -> python-updater -> portage-2.1.2 -> python-2.4 (just take a look at the involved ebuilds). In order to get around it you need to get one of the last three installed first, and python-updater was the best candidate (as it's small and only used when directly invoked, so breaking it temporary isn't such a big deal). |

I am posting to this stale thread in the hopes of getting it into earlier search results for those upgrading old, decommissioned Gentoo boxes, or any Gentoo box that does not yet have python 2.4 on it. Not all Gentoo boxes have ready access to the Internet for frequent updates.
Genone explains the how and why of the circular python blockers, BRAVO. Great developer support. You saved the world from some more
Ubuntu systems.
Many thanks,
John |
