update failed

I tried to update cyberpanel and the update fails. this is what i get:

modulenotfounderror: no module named ‘sleep’

Any suggestions please?

thank you

UPDATE: I managed to update the panel.
The error log though is flooded with:

Failed to open the real time report: /tmp/lshttpd/.rtreport!

Could it be a permission issue?

rm -rf /tmp/lshttpd/*

Server will then generate new report files.

I 'm afraid it didn’t work. The panel is installed on openlitespeed. Does it make a difference?

Here is what helped me.
Check are you on OLS or Ent license.
I was on free ENT license and done update and lost connection to website.
I figured out that with update, I lost license as well (admin panel → serverstatus was empty from my license)
That printed me also logs “Failed to open the real time report: /tmp/lshttpd/.rtreport!”
The reason is that report reffers to /dev/shm/lsws/.rtreport in ENT edition, but in OLS it reffers to /dev/shm/ols/.rtreport
You can check that by command: ls -la /tmp/lshttpd/
So when i put again license, all went back to normal.
I hope that help to anyone.
