python blocking python-updater

[malnar]

Trying to run revdep-rebuild I run into a problem with python blocking python-updater. I know I shouldn't remove python because it is used by portage, but I went ahead and gave it a try anyways. Funny thing is, I don't have the version of python installed which revdep-rebuild is claiming blocks python-updater. Looking for advice on how to proceed.

Code: Select all

revdep-rebuild failed to emerge all packages
you have the following choices:

- if emerge failed during the build, fix the problems and re-run revdep-rebuild
    or
- use -X or --package-names as first argument (trys to rebuild package, not exact
  ebuild)
    or
- set ACCEPT_KEYWORDS="~<your platform>" and/or /etc/portage/package.unmask
  (and remove /root/.revdep-rebuild.5_order to be evaluated again)
    or
- modify the above emerge command and run it manually
    or
- compile or unmerge unsatisfied packages manually, remove temporary files and
  try again (you can edit package/ebuild list first)

To remove temporary files, please run:
rm /root/.revdep-rebuild*.?_*

Code: Select all

# emerge -aC python

Would you like to unmerge these packages? [Yes/No] no

Quitting.

[nixnut]

You do have the python version python-updater is complaining about.
<dev-lang/python-2.3.6-r2 (note the '<') means any version earlier than 2.3.6-r2 and dev-lang/python-2.3.5-r3 fits the bill.
try emerge -C =dev-lang/python-2.3.5-r3 and then run revdep-rebuild again

worked like a charm. thank you.

Hi,

I have a similar block:

Code: Select all

# emerge --oneshot --ask -v app-admin/python-updater

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R   ] app-admin/python-updater-0.2  0 kB

Total: 1 package (1 reinstall, 1 block), Size of downloads: 0 kB

!!! Error: The above package list contains packages which cannot be installed

For more information about Blocked Packages, please refer to the following
section of the Gentoo Linux x86 Handbook (architecture is irrelevant):

http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?full=1#blocked

The problem is that when I try to remove this blocking package portage says it does not exist:

Code: Select all

# emerge -C =dev-lang/python2.3.6-r2

--- Couldn't find '=dev-lang/python2.3.6-r2' to unmerge.

>>> No packages selected for removal by unmerge

Some where in portage, in some file, there is a reference to this version of python which is causing portage to think it is installed, and it is blocking app-admin/python-updater-0.2, which is required by newer versions of python: Where might one look?

[malnar]

Run "emerge -pC python". You'll get a line similar to "selected: 2.3.5-r3 2.4.4-r4". This tells you which versions you have installed. Anything before 2.3.6-r2 is a candidate for blocking and must be removed. In my case it was 2.3.5-r3. In your case it may be different. I then had to run "emerge -C dev-lang/python-2.3.5-r3" and *not* "emerge -C dev-lang/python-2.3.6-r2" as one would expect.

[lab]

It turns out python-2.3.5-r3 was the actual blocking package. When I removed it, everything was happy. I have no idea why it was reporting a different blocking version that did not exist.

Code: Select all

# emerge -pC python

>>> These are the packages that would be unmerged:

[John R. Graham]

You had

Code: Select all

[blocks B     ] <dev-lang/python-2.3.6-r2 (is blocking app-admin/python-updater-0.2)

in your emerge output. The "<" symbol denotes any version less than the listed version. In other words python-updater-0.2 needs a version of python at least as new as 2.3.6-r2. Clear?

[ElCondor]

I have a similar problem (on a system not touched for over 2 years), exept that I only have 2.3.5 installed:

www ~ # emerge -pC python

>>> These are the packages that I would unmerge:

!!! Trying to unmerge package(s) in system profile. 'dev-lang/python'

dev-lang/python
selected: 2.3.5-r2

>>> 'Protected' and 'omitted' packages will not be removed.

when I try to upgrade I get (shortened):

www etc # emerge -pv python

[nixnut]

Update python first to 2.4.4-r5. If you don't and unmerge your current python version you'll find that portage stops working.
Once you've installed the new python version you can unmerge the older one. After that you can update world. And don't forget to run python-updater afterwards.

I have the same problem (only one version of Python installed, it it is blocking the new version (WTF)), tried this suggestion and then just simply:

Code: Select all

emerge python

It is compiling now.

This is another one of those Gentoo-isms that bugs me. Why are there so many obscure solutions like this? I know I wouldn't have figured this one out on my own.

[melbaum]

Now let's just suppose that emerge is already not working...
/usr/bin/emerge: /usr/bin/python: bad interpreter: No such file or directory
Am I back to a fresh install? It's a test system so not a big disaster, but I'm wondering if there's a better way.

[John R. Graham]

No, follow [post=4267052]NeddySeagoon's advice[/post] on another post and you should be able to recover. Prebuilt binaries of critical packages are available on Gentoo Tinderbox.

- John

[melbaum]

Thanks. That looked great, but no matter what I do I still get:
/usr/bin/python: error while loading shared libraries: libpython2.3.so.1.0: cannot open shared object file: No such file or directory
I've installed python2.4 as well as portage from Tinderbox, so I don't see why it still looks for libpython2.3
python-config gives me the same error.

just to be sure...
ls -l /usr/lib/portage/bin/emerge
-rwxr-xr-x 1 root root 223616 Sep 20 01:50 /usr/lib/portage/bin/emerge

ls -l /usr/lib/libpython2.4.so*
lrwxrwxrwx 1 root root 19 Oct 1 02:12 /usr/lib/libpython2.4.so -> libpython2.4.so.1.0
-r-xr-xr-x 1 root root 995808 May 15 18:17 /usr/lib/libpython2.4.so.1.0

So after an hour of nothing I did another unthinkable and linked libpython2.3.so.1.0 to libpython2.4.so.1.0
Now python-2.4 has emerged successfully and python-updater seems to be doing something like emerge system.
I'll kill the link when it's over, but this is certainly the wrong way to do it. like I said, it's a test system.
Any thoughts what I should have done to recover at this stage?

[John R. Graham]

Probably your environment is just out of date. You might try removing that unthinkable symlink and running

Code: Select all

env-update
source /etc/profile

Betcha emerge works after that.

- John

[ElCondor]

okay, what I did was

Code: Select all

emerge --nodeps -v =dev-lang/python-2.4.4-r5

that way I got a new python, could unmerge the old one and update the rest of the system afterwards.
maybe I will have to revdep-rebuild (didn't check last night), but on the first look everything seems to work

* ElCondor pasa *

[melbaum]

I managed a little less gracefully. I copied the untared Tinderbox binaries into / , and then with emerge working I re-emerged python-2.4 and unmerged 2.3. Then I ran into the libexpat.so.0 nonsense and eventually got it all fixed with revdep-rebuild. m4 didn't build because of a missing symlink from /usr/bin/ar to /usr/bin/i686-pc-linux-gnu-ar . db was also troublesome.

Now I can do emerge -av world, but emerge -auDv world ends with:

[blocks B ] <dev-lang/python-2.3.6-r2 (is blocking app-admin/python-updater-0.2)

I already unmerged the old python. from /var/log/emerge.log:
1191192230: === Unmerging... (dev-lang/python-2.3.5-r3)
1191192280: >>> unmerge success: dev-lang/python-2.3.5-r3

emerge -Cp python has no mention of 2.3.5:

Curious... I'll try without the -D for now.

Can you upgrade it? emerge -av ="dev-lang/python-2.3.6-r2"
That should get rid of the 2.3.5 version without affecting the 2.4 slot.
2.3.6-r2 is masked ~x86, so don't forget: echo "dev-lang/python-2.3.6-r2" >>/etc/portage/package.keywords
If emerge is completely fried and "env-udpate && source /etc/profile" doesn't help, the only thing that worked for me was to install 2.4 from Tinderbox (above) and then re-emerge.

[taavetti]

melbaum,
Thanks for the reply. Emerging does not work....thought about Tinderbox but the time has come to reinstall.

I have been running the same (and stable) system for 3+ years - largely thanks to the Gentoo Discussion Forums. Whenever there has been a problem the Forums have had the answers.

There was a bit of a triple whammy lately with
1) a long-overdue upgrade
2) expat-2.0.x issues (that got worked out, thanks to the Forums)
3) power outage in the middle of a world emerge

Anyway, something got borked (finger pointing at me ). Don't mind doing a reinstall actually and I know I will learn something else new in the reinstall process.

Hello,

You do have the python version python-updater is complaining about.
<dev-lang/python-2.3.6-r2 (note the '<') means any version earlier than 2.3.6-r2 and dev-lang/python-2.3.5-r3 fits the bill.
try emerge -C =dev-lang/python-2.3.5-r3 and then run revdep-rebuild again

unmerging the 2.3 version of python also did the trick for me. Because my system is a fairly old installation (about 3 - 4 years) and I only run security updates I did a quick check with

Code: Select all

revdep-rebuild -p --library libpython2.3.so

and

Code: Select all

revdep-rebuild -p --library libpython2.3.so.1.0

to see if anything still depended on python 2.3 (on a binary level at least). It turned out only python 2.3 depended on the 2.3 libraries, which is fairly logical

Thanks to this thread for reassuring me that python 2.3 is not necessarily needed anymore.

Oh no, I have a similar problem...

I just rebuilt my system due to numerous problems, upgrading from 2005.something to 2007.0.

Everything seemed to go fine until I updated my system with -avuDN world

My computer now will not shutdown -r or even log into kde, I get:

usr/bin/xterm: Could not exec bin/bash: No such file or directory

and it goes back to login.

When I return to console, I have a message that states:
