Upgrade problems

I faced this problem during the upgrade of my erpnext. anyone can help ?

Use only
bench switch-to-branch version-13 --upgrade

thanks for your reply. still not working

bench switch-to-branch --upgrade version-13 frappe erpnext

I don’t think it’s the command , since I upgraded other servers with same command before

share the error log

I did . it’s on the main topic

go to apps/frappe and share the output of the command
git remote -v

upstream Sign in · GitLab (fetch)
upstream Sign in · GitLab (push)

can you check if branch version-13 exists in the repo ??

which repository ?

this repo of frappe …

oh , that’s not mine . someone else installed erpnext here .

ok make sure to use proper github repos before upgrading. Thanks

how exactly can I change it ? and what is the right one ? thank you
