我正在尝试进行新的单次提交，但出现错误：
gpg: DBG: Using CREATE_BREAKAWAY_FROM_JOB flag
gpg: can't connect to the agent: IPC connect call failed
gpg: keydb_search failed: No agent running
gpg: skipped "C4583B304CDA4CA0": No agent running
gpg: signing failed: No agent running
error: gpg failed to sign the data
有谁知道如何解决这个问题？
