NAME

6       opam admin-upgrade - Upgrades repository from earlier opam versions.
7

SYNOPSIS

9       opam admin upgrade [OPTION]...
10

DESCRIPTION

12       This command reads repositories from earlier opam versions, and
13       converts them to repositories suitable for the current opam version.
14       Packages might be created or renamed, and any compilers defined in the
15       old format ('compilers/' directory) will be turned into packages, using
16       a pre-defined hierarchy that assumes OCaml compilers.
17

OPTIONS

19       --clear-cache
20           Instead of running the upgrade, clear the cache of archive hashes
21           (held in ~/.cache), that is used to avoid re-downloading files to
22           obtain their hashes at every run.
23
24       -m URL, --mirror=URL
25           Don't overwrite the current repository, but put an upgraded mirror
26           in place in a subdirectory, with proper redirections. Needs the URL
27           the repository will be served from to put in the redirects (older
28           versions of opam don't understand relative redirects).
29

COMMON OPTIONS

31       These options are common to all commands.
32
33       --best-effort
34           Don't fail if all requested packages can't be installed: try to
35           install as many as possible. Note that not all external solvers may
36           support this option (recent versions of aspcud or mccs should).
37
38       --color=WHEN
39           Colorize the output. WHEN must be one of `always', `never' or
40           `auto'.
41
42       --criteria=CRITERIA
43           Specify user preferences for dependency solving for this run.
44           Overrides both $OPAMCRITERIA and $OPAMUPGRADECRITERIA. For details
45           on the supported language, and the external solvers available, see
46           http://opam.ocaml.org/doc/Specifying_Solver_Preferences.html. A
47           general guide to using solver preferences can be found at
48           http://www.dicosmo.org/Articles/usercriteria.pdf.
49
50       --cudf=FILENAME
51           Debug option: Save the CUDF requests sent to the solver to
52           FILENAME-<n>.cudf.
53
54       --debug
55           Print debug message to stderr. This is equivalent to setting
56           $OPAMDEBUG to "true".
57
58       --debug-level=LEVEL
59           Like --debug, but allows specifying the debug level (--debug sets
60           it to 1). Equivalent to setting $OPAMDEBUG to a positive integer.
61
62       --git-version
63           Print the git version of opam, if set (i.e. you are using a
64           development version), and exit.
65
66       --help[=FMT] (default=auto)
67           Show this help in format FMT. The value FMT must be one of `auto',
68           `pager', `groff' or `plain'. With `auto', the format is `pager` or
69           `plain' whenever the TERM env var is `dumb' or undefined.
70
71       --ignore-pin-depends
72           Ignore extra pins required by packages that get pinned, either
73           manually through opam pin or through opam install DIR. This is
74           equivalent to setting IGNOREPINDEPENDS=true.
75
76       --json=FILENAME
77           Save the results of the opam run in a computer-readable file. If
78           the filename contains the character `%', it will be replaced by an
79           index that doesn't overwrite an existing file. Similar to setting
80           the $OPAMJSON variable.
81
82       --no-auto-upgrade
83           When configuring or updating a repository that is written for an
84           earlier opam version (1.2), opam internally converts it to the
85           current format. This disables this behaviour. Note that
86           repositories should define their format version in a 'repo' file at
87           their root, or they will be assumed to be in the older format. It
88           is, in any case, preferable to upgrade the repositories manually
89           using opam admin upgrade [--mirror URL] when possible.
90
91       -q, --quiet
92           Disables --verbose.
93
94       --root=ROOT
95           Use ROOT as the current root path. This is equivalent to setting
96           $OPAMROOT to ROOT.
97
98       --safe, --readonly
99           Make sure nothing will be automatically updated or rewritten.
100           Useful for calling from completion scripts, for example. Will fail
101           whenever such an operation is needed ; also avoids waiting for
102           locks, skips interactive questions and overrides the $OPAMDEBUG
103           variable.
104
105       --solver=CMD
106           Specify the CUDF solver to use for resolving package installation
107           problems. This is either a predefined solver (this version of opam
108           supports builtin-mccs+lp(), builtin-mccs+glpk, aspcud, mccs,
109           aspcud-old, packup), or a custom command that should contain the
110           variables %{input}%, %{output}%, %{criteria}%, and optionally
111           %{timeout}%.
112
113       --strict
114           Fail whenever an error is found in a package definition or a
115           configuration file. The default is to continue silently if
116           possible.
117
118       --switch=SWITCH
119           Use SWITCH as the current compiler switch. This is equivalent to
120           setting $OPAMSWITCH to SWITCH.
121
122       --use-internal-solver, --no-aspcud
123           Disable any external solver, and use the built-in one (this
124           requires that opam has been compiled with a built-in solver).
125
126       -v, --verbose
127           Be more verbose. One -v shows all package commands, repeat to also
128           display commands called internally (e.g. tar, curl, patch etc.)
129           Repeating n times is equivalent to setting $OPAMVERBOSE to "n".
130
131       --version
132           Show version information.
133
134       -w, --working-dir
135           Whenever updating packages that are bound to a local,
136           version-controlled directory, update to the current working state
137           of their source instead of the last committed state, or the ref
138           they are pointing to. This only affects packages explicitly listed
139           on the command-line.
140
141       -y, --yes
142           Answer yes to all yes/no questions without prompting. This is
143           equivalent to setting $OPAMYES to "true".
144

ENVIRONMENT VARIABLES

146       Opam makes use of the environment variables listed here. Boolean
147       variables should be set to "0", "no", "false" or the empty string to
148       disable, "1", "yes" or "true" to enable.
149
150       OPAMCOLOR, when set to always or never, sets a default value for the
151       --color option.
152
153       OPAMCRITERIA specifies user preferences for dependency solving. The
154       default value depends on the solver version, use `config report` to
155       know the current setting. See also option --criteria
156
157       OPAMCURL can be used to select a given 'curl' program. See OPAMFETCH
158       for more options.
159
160       OPAMDEBUG see options `--debug' and `--debug-level'.
161
162       OPAMDOWNLOADJOBS sets the maximum number of simultaneous downloads.
163
164       OPAMERRLOGLEN sets the number of log lines printed when a sub-process
165       fails. 0 to print all.
166
167       OPAMEXTERNALSOLVER see option `--solver'.
168
169       OPAMFETCH specifies how to download files: either `wget', `curl' or a
170       custom command where variables %{url}%, %{out}%, %{retry}%,
171       %{compress}% and %{checksum}% will be replaced. Overrides the
172       'download-command' value from the main config file.
173
174       OPAMJOBS sets the maximum number of parallel workers to run.
175
176       OPAMJSON log json output to the given file (use character `%' to index
177       the files)
178
179       OPAMLOCK see option `--lock'.
180
181       OPAMNOAUTOUPGRADE disables automatic internal upgrade of repositories
182       in an earlier format to the current one, on 'update' or 'init'.
183
184       OPAMKEEPLOGS tells opam to not remove some temporary command logs and
185       some backups. This skips some finalisers and may also help to get more
186       reliable backtraces
187
188       OPAMLOCKRETRIES sets the number of tries after which OPAM gives up
189       acquiring its lock and fails. <= 0 means infinite wait.
190
191       OPAMNO answer no to any question asked.
192
193       OPAMNOASPCUD see option `--no-aspcud'.

195       OPAMNOSELFUPGRADE see option `--no-self-upgrade'.
196
197       OPAMPINKINDAUTO sets whether version control systems should be detected
198       when pinning to a local path. Enabled by default since 1.3.0.
199
200       OPAMREQUIRECHECKSUMS Enables option `--require-checksums' when
201       available (e.g. for `opam install`).
202
203       OPAMRETRY sets the number of tries before failing downloads.
204
205       OPAMROOT see option `--root'. This is automatically set by `opam env
206       --root=DIR --set-root'.
207
208       OPAMROOTISOK don't complain when running as root.
209
210       OPAMSAFE see option `--safe'
211
212       OPAMSKIPVERSIONCHECKS bypasses some version checks. Unsafe, for
213       compatibility testing only.
214
215       OPAMSOLVERTIMEOUT change the time allowance of the solver. Default is
216       60.0, set to 0 for unlimited. Note that all solvers may not support
217       this option.
218
219       OPAMSTATUSLINE display a dynamic status line showing what's currently
220       going on on the terminal. (one of one of `always', `never' or `auto')
221
222       OPAMSWITCH see option `--switch'. Automatically set by `opam env
223       --switch=SWITCH --set-switch'.
224
225       OPAMUPGRADECRITERIA specifies user preferences for dependency solving
226       when performing an upgrade. Overrides OPAMCRITERIA in upgrades if both
227       are set. See also option --criteria
228
229       OPAMUSEINTERNALSOLVER see option `--use-internal-solver'.
230
231       OPAMUTF8 use UTF8 characters in output (one of one of `always', `never'
232       or `auto'). By default `auto', which is determined from the locale).
233
234       OPAMUTF8MSGS use extended UTF8 characters (camels) in opam messages.
235       Implies OPAMUTF8. This is set by default on OSX only.
236
237       OPAMVAR_var overrides the contents of the variable var when
238       substituting `%{var}%` strings in `opam` files.
239
240       OPAMVAR_package_var overrides the contents of the variable package:var
241       when substituting `%{package:var}%` strings in `opam` files.
242
243       OPAMVERBOSE see option `--verbose'.
244
245       OPAMYES see option `--yes'.
246

EXIT STATUS

248       As an exception to the following, the `exec' command returns 127 if the
249       command was not found or couldn't be executed, and the command's exit
250       value otherwise.
251
252       0   Success, or true for boolean queries.
253
254       1   False. Returned when a boolean return value is expected, e.g. when
255           running with --check, or for queries like opam lint.
256
257       2   Bad command-line arguments, or command-line arguments pointing to
258           an invalid context (e.g. file not following the expected format).
259
260       5   Not found. You requested something (package, version, repository,
261           etc.) that couldn't be found.
262
263       10  Aborted. The operation required confirmation, which wasn't given.
264
265       15  Could not acquire the locks required for the operation.
266
267       20  There is no solution to the user request. This can be caused by
268           asking to install two incompatible packages, for example.
269
270       30  Error in package definition, or other metadata files. Using
271           --strict raises this error more often.
272
273       31  Package script error. Some package operations were unsuccessful.
274           This may be an error in the packages or an incompatibility with
275           your system. This can be a partial error.
276
277       40  Sync error. Could not fetch some remotes from the network. This can
278           be a partial error.
279
280       50  Configuration error. Opam or system configuration doesn't allow
281           operation, and needs fixing.
282
283       60  Solver failure. The solver failed to return a sound answer. It can
284           be due to a broken external solver, or an error in solver
285           configuration.
286
287       99  Internal error. Something went wrong, likely due to a bug in opam
288           itself.
289
290       130 User interrupt. SIGINT was received, generally due to the user
291           pressing Ctrl-C.
