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).

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 zmedico 1.9 version present in the tree if possible. If your currently installed version of
49     python reported by <c>python -V</c> is less than 2.4 then you must choose a
50     version of portage that is compatible with it. If you have at least python 2.3
51     then use <e>portage-2.1.1.tar.bz2</e>. If you have python 2.2 then use
52     <e>portage-2.0.51.22.tar.bz2</e>.
53 rane 1.6 </p>
54    
55     <p>
56     Depending on the exact reason portage doesn't work for you anymore it may still
57 genone 1.1 be possible to use it to fetch the tarball for you, so as a first step please
58 rane 1.6 try to run <c>emerge --fetchonly sys-apps/portage</c>, only if that doesn't
59     work you have to manually fetch the tarball with:
60     </p>
61    
62     <pre caption="Fetching portage tarball with wget">
63     # <i>wget -P /usr/portage/distfiles http://distfiles.gentoo.org/distfiles/portage-2.1.1.tar.bz2</i>
64 genone 1.1 </pre>
65 rane 1.6
66     <p>
67     After that you should have the tarball available as
68     <path>/usr/portage/distfiles/portage-2.1.1.tar.bz2</path>.
69     </p>

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