Quick fix for e2fsprogs, com_err, and ss blockers

papapenguin · l33t Joined: 20 Sep 2005 Posts: 694 Location: Bellevue

ok, so what I did was to re-emerge ss and com_err

which brought back the 'old' versions...

then I forced the new version of e2fsprogs, then got rid of ss , com_err and e2fsprogs, removed the old version of revdep-rebuild and ran revdep-rebuild again...

that got me back!

0/ make backups:
qpkg sys-libs/ss; qpkg sys-libs/com_err
1/ paludis -u sys-libs/ss --permit-unsafe-uninstalls
2/ paludis -u sys-libs/com_err --permit-unsafe-uninstalls
3/ paludis -i sys-fs/e2fsprogs

- blockers removed - I've still not verifired that really nothing si broken but it looks good for now

I am not an expert here and by the looks of it trying to resolve it may strand you with an unbootable system.

No suggested fixes worked here. I always had to revdep-rebuild to prevent me from breaking my system. Besides neither mit-krb5 nor nfs-utils are on my system. So another package might cause the blockers.

Is it safe to assume that buying myself some time and wait until the bug is being resolved while packages waiting to be updated keep piling up behind those blockers might be a good idea?

What ever package depends on ss/com_err will now be asking for e2fsprogs. From what I can tell ss/com_err is being merged into and replaced by e2fsprogs so more and more packages will ask for it. Try running this to see what packages depend on ss/com_err:

Thanks richard.scott, I'll give it another try.
Are you suggesting that there will be no other way to deal with this block but to work around it like this and cross your fingers on reboot?

I apologize if this may sound a little rude. Is it "better safe tha sorry" or "no risk no fun"?

EDIT:seems there were no other packages depending on ss or com_err - so far so good; the blocks have disappeared and I could reboot - I will as soon as necessary - it should be fine - this sure scared me quite a bit; thanks again

I've had 12 systems that I've upgraded with these 3 steps and they've all worked ok :-)

The only issue people seem to have is if they've unmerged things before downloading the installation tarballs (i.e. emerge -f e2fsprogs).
wget needs ssl which needs ss/com_err (or something like that) so when you remove ss/com_err it stops wget from working so you can't download e2fsprogs to fix your error.

For some reason people think that linux is like windows and try rebooting to fix things.....
If you reboot without either ss/com_err or e2fsprogs then it may not come backup! :roll:

after I did the "emerge -C com_err", I then was not able to emerge e2fsprogs and move on. I noticed wget was failing because it could not find com_err. I looked at the file it wanted to download e2fsprogs-libs-1.41.tar.gz and I popped into firefox and manually downloaded the file from http://gentoo.osuosl.org/distfiles/e2fstprogs-libs-1.41.tar.gz into /usr/portage/distfiles. Then I could re-emerge e2fsprogs, now I can update my system.

During the emerge of the e2fsprogs-libs package I saw com_err scroll by. It looks like it was moved into this package.

im already past this, but I would say if I had to do it again, I would do something like this first.

emerge -f e2fsprogs-libs
emerge -C com_err
emerge e2fsprogs-libs

I had those blockers on my amd64 system before I ~amd64 keyworded e2fsprogs-libs. I also had <=....mit-krb5...r2

After emerging e2fsprogs, it installed fine but pulled in com_err and ss. I then keyworded in =app-crypt/mit-krb5-1.6.3-r4 and removed the <=app-crypt/mit-krb5-1.6.3-r2.
Emerge -C com_err ss e2fsprogs.
Emerge -v mit-krb5 and thought my problems were solved. It looked as if e2fsprogs and e2fsprogs-libs were installedalongside mit-krb5. Good, I thought.
Revdep-rebuild will rebuild anything broken? Nah, but maybe point the right way. For me it was a couple programs dynamically linking against libext2fs.so.2. Testdisk and photorec. The package was testdisk(testdisk and photorec) that failed.
Well, I noticed I still had problems. I looked to see what emerge -tav testdisk would show.
Dreaded blockers. Wanted to install B ss and B com_err again with mention to both programs blocking e2fsprogs-libs. I removed e2fsprogs-libs from package.keywords and removed e2fsprogs-libs, then emerged e2fsprogs,

Yes, e2fsprogs was one of my blockers, but the actual package that had it was e2fsprogs-libs. That is the package that was causing the upset for me.

I am seeing more of this kind of thing, where one package blocks another because a library got merged into it. Think I have seen that 3 times lately. one was mktemp got put into some other package, the e2fsprogs-libs thing and one other that had the same thing. I guess I am going to have to start paying more attention to the files that each package has from now on when I see a blocker.

Doesn't seem like anyone else has had this problem, but I did, so just wanted to post this.

When following the steps at the beginning of this tread, the final emerge e2fsprogs would fail.

To solve this, I re-emerged e2fsprogs-libs, and then it worked.

I thought that I'd mention that on my initial attempt at this (I'm on machine #3 now) I unmerged ss and com_err before trying anything else. To my horror, wget wasn't able to fetch anything any more! Fortunately, I was able to get the packages from another source, everythings working now.

It might be nice to add an "emerge -uDavF system" (or even just a "emerge -uDavF e2fsprogs e2fsprogs-libs ss com_err" line) to the guide in case people hit the same problem.

On my server, I have it "emerge --sync" in cron.daily, so it puts its load on the Gentoo servers in the middle of the night, at least the US middle of the night. In the same script, I "emerge -fuDN world" so that it also fetches the source during off-hours. As a side-effect, it granted me some forgiveness from this problem.

The following worked perfect on my system...

well i dont have another gentoo box handy so i tried the binary approach, for whatever reason emerge -K and emerge --usepkg seem to ignore all attempts to use the binary file i put in the /usr/portage/packages dir, not sure why... i tried to just extract it and im guessing its not compatible with my kernel, i get the following:
