add update_cache: yes and cache_valid_time: 3600 on "Install Proxmox VE and related packages"

Looks like a bunch of extra commits are included here that conflict with already merged changes.

Can you try rebasing your branch against develop? Locally, I believe you should run the following.

# adds a new location that you can pull changes from, but doesn't automatically pull them
git remote add upstream https://github.com/lae/ansible-role-proxmox.git
# fetches changes from upstream, doesn't automatically add them to your local branches/changes
git fetch upstream
 # starts an interactive rebase session for your current local branch
git rebase -i upstream/develop
# remove the unnecessary commits by changing "pick" to "drop"
# save, and git should attempt to apply the relevant commit
# then overwrite the branch changes for this PR
git push --force

edit: fixed remote to be https
