31     <p>
32     This section will tell you how to manually update/fix your portage installation
33     in case you can't run <c>emerge sys-apps/portage</c>. While not hard it is
34     still to be done with great care, so please follow the listed steps exactly
35     (but apply common sense when necessary).
36     </p>

41     <title>Getting a portage tarball</title>
42     <body>
43 rane 1.6
44     <p>
45     The first step to do is to get the tarball of a current portage version. In the
46     following text we will use <e>portage-2.1.1</e> as an example (as this is the
47     current stable version at the time of this writing), please replace that with a
48 genone 1.10 version present in the tree if possible.
49 rane 1.6 </p>
50 genone 1.10 <warn>
51     If your currently installed version of python reported by <c>python -V</c>
52     is less than 2.4 then you must choose a version of portage that is compatible with
53     it. If you have at least python 2.3 then use <e>portage-2.1.1.tar.bz2</e>. If
54     you have python 2.2 then use <e>portage-2.0.51.22.tar.bz2</e>.
55     </warn>
56 rane 1.6
57     <p>
58     Depending on the exact reason portage doesn't work for you anymore it may still
59 genone 1.1 be possible to use it to fetch the tarball for you, so as a first step please
60 rane 1.6 try to run <c>emerge --fetchonly sys-apps/portage</c>, only if that doesn't
61     work you have to manually fetch the tarball with:
62     </p>
63    
64     <pre caption="Fetching portage tarball with wget">
65     # <i>wget -P /usr/portage/distfiles http://distfiles.gentoo.org/distfiles/portage-2.1.1.tar.bz2</i>
66 genone 1.1 </pre>
67 rane 1.6
68     <p>
69     After that you should have the tarball available as
70     <path>/usr/portage/distfiles/portage-2.1.1.tar.bz2</path>.
71     </p>
72    
73 genone 1.1 </body>

75     <section>
76     <title>Replacing the installed version</title>
77     <body>
78 rane 1.6
79     <p>
80     The next step is to unpack the tarball to a temporary location, using
81     <path>/root/portage-recover</path> as example the commands to do that are:
82     </p>
83    
84     <pre caption="Unpacking portage tarball">
85     # <i>cd /root</i>
86     # <i>mkdir portage-recover</i>
87     # <i>cd portage-recover</i>
88     # <i>tar xfj /usr/portage/distfiles/portage-2.1.1.tar.bz2</i>
89 genone 1.1 </pre>
90 rane 1.6
91     <p>
92     After you have done this it's just a matter of replacing the python and bash
93     files of your existing installation with the ones from the tarball (in most
94     cases anyway). To do so please run:
95     </p>
96    
97     <pre caption="Replacing installed files">
98     # <i>cd /root/portage-recover/portage-2.1.1</i>
99     # <i>cp -R pym bin /usr/lib/portage/</i>
100 genone 1.1 </pre>
101 rane 1.6
102 zmedico 1.11 <p>
103     If you are not using Gentoo on FreeBSD then you should remove the sed wrapper
104     script since it's not needed and it is known to cause problems with old
105     versions of bash:
106     </p>
107    
108     <pre caption="Removing the sed wrapper script">
109     # <i>rm -f /usr/lib/portage/bin/sed</i>
110     </pre>
111    
112 genone 1.7 <note>
113     If you accidently unmerged portage before or lost
114     <path>/etc/make.globals</path> for other reasons you should also copy
115     <path>cnf/make.globals</path> back into <path>/etc</path>, otherwise
116     portage might behave in strange ways.
117     </note>
118 zmedico 1.8 <note>
119     If the previous version of portage was less than 2.1 then you should now run
120     <c>emerge --metadata</c> before continuing to the next step. This is necessary
121     in order to convert the ebuild metadata to the new format that is used by
122     portage 2.1 and above. It is okay to run this command even if you are not sure
123     what the previous version of portage was.
124     </note>
125 genone 1.7
126 rane 1.6 <p>
127     Now you should have a working portage install again. To ensure a consistent
128 genone 1.1 system state however you should now run <c>emerge sys-apps/portage</c> again
129 rane 1.6 immediately.
130     </p>
131    
132     <p>
133     If you get a <e>command not found</e> error message when you try to run
134     <c>emerge</c> you have to recreate the symlink:
135     </p>
136    
137     <pre caption="Recreating the emerge symlink">
138     # <i>ln -s ../lib/portage/bin/emerge /usr/bin/emerge</i>
139 genone 1.4 </pre>
140 rane 1.6
141     <p>
142     If these steps didn't work for you your problem is likely not a broken portage
143     installation but something else beyond the scope of this document. Please
144     recheck the <uri link="/proj/en/portage/doc/common-problems.xml">list of common
145     problems</uri> and also look in <uri
146     link="http://bugs.gentoo.org">bugzilla</uri> if the problem is reported there.
