 Posted: Sat Oct 17, 2015 8:09 am Post subject: [Solved] transmission-daemon results in Segmentation Fault |
 |
|
After a recent "emerge -vDu world", transmission stopped working.
| Code: | # /etc/init.d/transmission-daemon start
* Caching service dependencies ... [ ok ]
* Starting transmission daemon ...
* start-stop-daemon: failed to start `/usr/bin/transmission-daemon' [ !! ]
* ERROR: transmission-daemon failed to start
|
And this is what happened when I ran it through gdb.
| Code: | # gdb transmission-daemon

I'm not sure how to proceed from here. I'd appreciate any suggestions.

Hi solamour
Looks like libnettle crashed, do you have updated/recompiled it along with transmission?
/usr/lib/libnettle.so.4 should belong to dev-libs/nettle, you can verify it and/or try to re-emerge it (just in case)

I re-emerged "nettle" (and "gnutls" as well while I was at it), but I ended up with the exactly same result. I wish I could get a little more info than just a simple error message.

/usr/lib/libnettle.so.4
I don't have this file above
but
/usr/lib/libnettle.so
/usr/lib/libnettle.so.6

Turned out that when I downgrade nettle from 3.1.1 to 2.7.1-r4, the problem went away.
As for "libnettle.so.4" and "/libnettle.so.6", it looks like different packages need different thing. For example, when I tried to unmerge nettle, I noticed the following.
| Code: | * - /usr/lib/libnettle.so.6
* - /usr/lib/libnettle.so.6.1
* used by /usr/libexec/gpg2keys_curl (app-crypt/gnupg-2.0.28)
* used by /usr/libexec/gpg2keys_hkp (app-crypt/gnupg-2.0.28)
* - /usr/lib/libnettle.so.4
* - /usr/lib/libnettle.so.4.7
* used by /usr/lib/libcurl.so.4.3.0 (net-misc/curl-7.43.0)
* used by /usr/lib/libgnutls.so.28.41.9 (net-libs/gnutls-3.3.17.1)
* used by /usr/libexec/squid/basic_ncsa_auth (net-proxy/squid-3.5.6)
* used by 2 other files
* - /usr/lib/libhogweed.so.2
* - /usr/lib/libhogweed.so.2.5
* used by /usr/lib/libgnutls.so.28.41.9 (net-libs/gnutls-3.3.17.1)

I might need to settle with a lower version until someone more knowledgeable figures out what to do about it.

I unmerged nettle, removed all "/usr/lib/libnettle*", emerged nettle v3.1.1, did "revdep-rebuild", and transmission magically started working. I'm happy to know the problem went away, but I'm not sure I like this "magically" part.

I myself had this issue several times experiencing that 'revdep-rebuild' nor 'emerge@preserverd-rebuild' let the old lib go. I think it is a bug. May be some sort of indirections portage cannot recognize yet. The workaround to use
'emerge -C LIB'
is no magic: You gave portage the absolute hint it must go on without the old lib. The only thing to pay attention:
Do not purge any LIB of the toolchain! Better file a bug in this case! |
