[chirp_users] Yaesu FT-897D Upload Error

I can download from my Yaesu FT-897D successfully using CHIRP daily-20201221 on Linux - Debian GNU/Linux 10 (Python 2.7.16) but I cannot upload.

I get the following error message.

raise errors.RadioError("Failed to communicate with radio: %s" % e) RadioError: Failed to communicate with radio: Radio did not ack block 0

ERROR: ---------------- ERROR: Clone failed: Failed to communicate with radio: Radio did not ack block 0 ERROR: --- Exception Dialog: Failed to communicate with radio: Radio did not ack block 0 --- ERROR: None

Full errors in attachment.

Any suggestions?
