| 51 | 56 | If any package is marked "X" (to the left of the package) it means it is not |
| 52 | 57 | installable even in $ARCHIVE - you should check why this is so by attempting to |
| 53 | 58 | install it yourself, e.g. via aptitude, and see why it can't be installed. This |
| 54 | 59 | must be fixed before migration is attempted. For example, it may depend on a |
| 55 | package which is not yet in Debian. | |
| 60 | package which is not yet in Debian. Make sure you give the \`-t $ARCHIVE\` flag | |
| 61 | so it chooses packages from the correct archive. | |
| 56 | 62 | |
| 57 | One common reason, for an rdep, is that its dependency (on rust-${pkg}) is out | |
| 58 | of date - check the "depends" column above to see if this is the case. If so, | |
| 59 | you must upgrade it to the current version, by patching Cargo.toml to accept | |
| 60 | the new version of ${pkg} as a dependency. Of course, check that the build | |
| 61 | works - if it doesn't, then you'll need to further patch the source code of the | |
| 62 | rdep to use the API of the new version of ${pkg}. | |

| 64 | 70 | Alternatively, if any rdep is obsolete (i.e. nothing else depends on it) then |
| 65 | 71 | you should file a RM request to remove it from the Debian archive. See the |
