emerge sync (update portage)

flebber · 03-18-2006, 11:11 PM

Very easy question but I cannot find the answer in the docs (perhaps too simple). When I am updating portage the docs say to

Quote:

emerge sync

however I am doing this and receiving a message saying

Quote:

* An update to portage is available. It is _highly_ recommended
* that you update portage now, before any other packages are updated.
* Please do so and then update ALL of your configuration files.

But this is what I thought I was doing.....I can emerge --update world but I assumed that was only updating installed files not portage or system files .

emerge sync doesn't update any packages on your system... think of it only as updating what's available in the 'catalogue'..

emerge world is the process which does the actual updating.
I suggest you review the gentoo doc's here, expecially the portage section. They are very helpful.

cheers

Yes, unfortunately portage is both the name of the package management system on Gentoo (including emerge, among others) and the name of the list of packages available for installation. When you see the "an update to portage is available" message, it is encouraging you to upgrade your package management software, either through 'emerge --oneshot portage' or through 'emerge -uD world'.

I just re-read your post and I think I may have misunderstood your question

I think you're what is confusing you (and yeah I can see how it can) ...is that while `emerge sync` populates the portage tree (w/ ebuilds) ..`emerge portage` updates the app/structure itself.

cheers

woops, didn't notice Matir's comments before I re-responded (so - yeah what Matir said

)

yes it was too simple "emerge portage" was the solution, thanks

When you do the normal upgrade after syncing your portage tree, it will upgrade portage and restart the emerge. You don't "have" to seperately upgrade portage.

I believe that this is what you are looking for.

Code:

$ emerge --sync
$ emerge --update world

Alternately

Code:

$ emerge --sync
$ emerge --update --deep world

These commands will update the portage tree and update all applications on the system that are managed by portage. This includes security updates, bugfixes, and feature enhancements.

From the message after emerge --sync finished:

Quote:

...that you update portage now, before any other packages are updated. ...

The first thing to do would be:
emerge -a sys-apps/portage
to update portage as suggested.
This will only take seconds...
Only then run any other emerge operation like:
emerge -au world

I updated portage but cannot complete update world due to one package. I receive a similar error to this .

Quote:

!!! Digest verification Failed:
!!! /usr/portage/distfiles/db-4.2.52.tar.gz
!!! Reason: Failed on MD5 verification

Is there a way around so I can complete

The digest (integrity-check) failed - might have been a corrupted download.
delete the file db-4.2.52.tar.gz from /usr/portage/distfiles and download it again with:
emerge -af sys-libs/db
(I believe that's what it is you wanted to emerge, but failed...)
and then start the emerge command you were originally running again -
or download it "by hand" and copy it there
