Facing fatal error in module 2

error: could not lock config file .git/config: File exists
fatal: could not set ‘remote.ME_QEATS_REVIEW_MP_MODULE_FACEBOOK_SHARE_FROM_APK_STUB.url’ to ‘git@gitlab.crio.do:ME_QEATS_REVIEW_MP_STUBS/ME_QEATS_REVIEW_MP_MODULE_FACEBOOK_SHARE_FROM_APK_STUB.git’
Can anyone help me get past this error I have been trying to solve this since yesterday evening but am unable to do it

Its looks like you haven’t set remote correctly. Read the setup instruction again
