If I try to install python-tevent on an x86_64 machine, it tries to pull in the 32-bit libtevent: # yum install python-tevent Loaded plugins: auto-update-debuginfo, langpacks, refresh-packagekit Resolving Dependencies --> Running transaction check ---> Package python-tevent.x86_64 0:0.9.18-1.fc19 will be installed --> Processing Dependency: libtevent = 0.9.18-1.fc19 for package: python-tevent-0.9.18-1.fc19.x86_64 --> Running transaction check ---> Package libtevent.i686 0:0.9.18-1.fc19 will be installed --> Processing Dependency: libtalloc.so.2(TALLOC_2.0.2) for package: libtevent-0.9.18-1.fc19.i686 --> Processing Dependency: libtalloc.so.2 for package: libtevent-0.9.18-1.fc19.i686 --> Processing Dependency: libdl.so.2 for package: libtevent-0.9.18-1.fc19.i686 --> Processing Dependency: libcrypt.so.1 for package: libtevent-0.9.18-1.fc19.i686 --> Processing Dependency: libc.so.6(GLIBC_2.15) for package: libtevent-0.9.18-1.fc19.i686 --> Running transaction check ---> Package glibc.i686 0:2.17-4.fc19 will be installed --> Processing Dependency: libfreebl3.so(NSSRAWHASH_3.12.3) for package: glibc-2.17-4.fc19.i686 --> Processing Dependency: libfreebl3.so for package: glibc-2.17-4.fc19.i686 ---> Package libtalloc.i686 0:2.0.8-2.fc19 will be installed --> Running transaction check ---> Package nss-softokn-freebl.i686 0:3.14.3-1.fc19 will be installed --> Finished Dependency Resolution Error: Multilib version problems found. This often means that the root cause is something else and multilib version checking is just pointing out that there is a problem. Eg.: 1. You have an upgrade for libtevent which is missing some dependency that another package requires. Yum is trying to solve this by installing an older version of libtevent of the different architecture. If you exclude the bad architecture yum will tell you what the root cause is (which package requires what). You can try redoing the upgrade with --exclude libtevent.otherarch ... this should give you an error message showing the root cause of the problem. 2. You have multiple architectures of libtevent installed, but yum can only see an upgrade for one of those architectures. If you don't want/need both architectures anymore then you can remove the one with the missing update and everything will work. 3. You have duplicate versions of libtevent installed already. You can use "yum check" to get yum show these errors. ...you can also use --setopt=protected_multilib=false to remove this checking, however this is almost never the correct thing to do as something else is very likely to go wrong (often causing much more problems). Protected multilib versions: libtevent-0.9.18-1.fc19.i686 != libtevent-0.9.18-2.fc19.x86_64 Error: Protected multilib versions: nss-softokn-freebl-3.14.3-1.fc19.i686 != nss-softokn-freebl-3.15-3.fc19.x86_64
I think the problem was that either repo was out of sync or the nss update went from testing to stable sooner than tevent update did. Does the problem still persist? Does it go away if you toggle the state of updates-testing on your machine? The tevent packaging has not changed in ages and we've never seen this problem. Anyway, I'll be afk next week, so I won't reply to the bug report, but if my suspiction is correct, then I'm sure either Simo or Andreas would close this report.
$ rpm -qp --requires python-tevent-0.9.18-1.fc19.x86_64.rpm | grep ^libtevent\ warning: python-tevent-0.9.18-1.fc19.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID fb4b18e6: NOKEY libtevent = 0.9.18-1.fc19 I believe that should have a %{?_isa} somewhere...
You're quite right, of course, that there's a repository out of sync. But with the following fixed Requires, the output from yum is a whole lot clearer about that, because it doesn't go off into the weeds trying to install a completely wrong package. -Requires: libtevent = %{version}-%{release} +Requires: libtevent%{?_isa} = %{version}-%{release} Error: Package: python-tevent-0.9.18-1.fc19.x86_64 (/python-tevent-0.9.18-1.fc19.x86_64) Requires: libtevent(x86-64) = 0.9.18-1.fc19 Installed: libtevent-0.9.18-2.fc19.x86_64 (@updates-testing) libtevent(x86-64) = 0.9.18-2.fc19 Available: libtevent-0.9.18-1.fc19.x86_64 (fedora) libtevent(x86-64) = 0.9.18-1.fc19 You could try using --skip-broken to work around the problem You can see it's correctly failing to find the libtevent(x86_64) package that it wants, telling me so, and bailing out — rather than trying to install an i686 version instead and rapidly going downhill from there.
I've fixed this in the Rawhide branch. I'll leave it up to Jakub and Simo to decide if it's important enough to backport to F19/F18.
