[gentoo-user] One package is blocking another?

[gentoo-user] One package is blocking another?

[Jayson Smith]

Hi,
Several days ago I did an 'emerge --ask --nospinner -u world' to update my
software as normal, but was told that ftpbase-0.00 was blocking
proftpd-1.something.  What, exactly, does this mean and what do I do about
it?  I want to continue using Proftpd, and don't know what Ftpbase is.  Any
help would be greatly appreciated.
Thanks,
Jayson.

Hello,

Blocking means that a package prevents other package from being installed.
I guess you already figured that out... :)

Quote from man pages should be quite clear (if not, ask :), it follows.

>From man emerge
"
[blocks B ] app-text/dos2unix (from pkg app-text/hd2u-0.8.0)
       Dos2unix is Blocking hd2u  from  being  emerged.   Blockers  are
       defined  when  two  packages  will clobber each others files, or
       otherwise cause some form of breakage in your system.   However,
       blockers  usually  do  not  need  to  be  simultaneously emerged
       because they usually provide the same functionality.
"

When I've got a block, I unmerge the blocking package (emerge -C ftpbase
in your case) and then emerge package I originally wanted (emerge proftpd).
I'm not sure if there's an other way to do this, but just unmerging has
worked for me so far.

unmerge the old proftpd version, emerge the new proftpd version. For some
reasons, this will now install "ftpbase" and "proftpd". The configs are
not altered, so no worry.  Works fine for me (I am running www.proftpd.de)

Hello Jayson Smith

I had the same problem. I solved it with:

host# emerge --nodeps --update net-ftp/proftpd
and than
host# emerge --deep --update world


I hope this is the right way to solve the problem.

Andy comments?

I often find that unmerging package A allows you to emerge B, after
which you may be able to emerge A again with no conflict occurring.
Worth a try.

Hmmm, ... IMHO this makes the blocking senseless.

The reason that the package was blocked was (from the changelog):

 08 Jul 2005; Gustavo Felisberto <humpback@gentoo.org>;
  +proftpd-1.2.10-r6.ebuild:
  New revision that uses the new net-ftp/ftpbase. Nice work there UberLord.

The ftpbase functionality was removed from this version of proftpd onwards. ftpbase was unable to be installed with previous versions of proftpd installed as they both use the same files (if I recall correctly). 
As Olli posted from the man page 
Blockers are defined when two packages will clobber each others files.

As emerge wants to build the dependencies of the new version of proftpd first (ie ftpbase), however it is unable to build ftpbase with the old version of proftpd installed.

Your method of updating is just fine and avoids this conflict.

I hope this makes sense,
Peter
