I got no more error and can successfully run bench update --upgrade,
But my version still V7.
I am trying to upgrade from v7.2.31 to latest version but no luck.
tried to upgrade to v8.x.x first with guidelines from here Unable to install ERPnext v8 due to pip v19 but also no luck. it still stuck with v7.2.31
result from git remote -v shows below;
upstream GitHub - bailabs/frappe-v7 (fetch)
upstream GitHub - bailabs/frappe-v7 (push)
I dont know if the problem because of this matter.
If anyone could give some guidance to upgrade, that would be appreciate it.
