[Koha] broken kohadevbox

Dear collegues, please help me to fix my serious problem with kohadevbox. I was updating sources from master using "git pull", but my internet connection got broken. Now I cannot update anymore even if I reset the master with git reset --hard origin/master vagrant@kohadevbox:kohaclone(master)$ git pull error: Unable to find 0dc1b622844f51da59bace572a04141733ba1f3a under http://git.koha-community.org/koha.git Cannot obtain needed tree 0dc1b622844f51da59bace572a04141733ba1f3a while processing commit 7636c68d769a1c2e62ced6aa9f2fbe12adf22c8d. error: fetch failed. How can I solve this? Radek
