Updating-your-SDK.md

@ -48,6 +48,19 @@ The old `update-core` script has been retired, see https://github.com/msys2/MSYS
An alternative method is to start `git-cmd.exe` from within the MSYS2 shell and run `pacman -Sy --needed msys2-runtime && pacman -S --needed pacman bash`. This ensures that no obsolete binary continues to be used after the
update.
## If All Else Fails
Occasionally, particularly if infrequently updated, you may find some blocking issue prevents update, e.g. some `gpg` key has 'expired'.
One option is a re-install, having saved your working repositories.
1. ensure any repositories you have worked on in `usr/src/` are up to date (e.g. `git fetch --all`, or your preferred invocation).
2. rename the top level SDK (e.g. `C:\git-sdk-64-Nov21\`).
3. install the SDK afresh.
4. copy your old `usr\src\git` repo, and others you worked on (as per 1. above), across to the new `usr\src\` location, having moved/renamed the SDK's copies out of the way.
5. you should now be able to hack on your git with the updated SDK.
6. at some later time, clean up the old copies.
