+1 I also ran into this. Pinning to 7.0.1 fixes it.

@ltshb I jsut managed to reproduce your error, should be working in a fix in the next couple of days or so.

[russoz]

@bgrande12 thanks for reporting. Could you please repeat the error using -vvvv to produce debugging information and paste that either here or in a gist/pastebin? TIA

[russoz]

Hi @ltshb @bgrande12

Would you please confirm whether the PR above fixes your issues? I managed to reproduce @ltshb 's case and added that as a testcase in unit tests. @bgrande12 if it still does not work for you, please send that extra-verbose output and I can make a testcase out of it. ;-)

@russoz I tried to use your PR to test but I couldn't, I'm not a profi with Ansible and might need guidance in order to test your PR.
Here what I did, I modified my ansible-galaxy requirements.yml file like this

collections:
  - name: git@github.com:ansible-collections/community.general.git
    type: git
    version: russoz-ansible:6821-snap-failure

and re-run ansible-galaxy install -r requirements.yml --force but I got the following error

hi @ltshb

Almost that. Try:

collections:
  - name: https://github.com/russoz-ansible/community.general.git
    type: git
    version: 6821-snap-failure

The working branches are on people's github accounts or projects (as in my case).
(Update: you must use the https URL or else it will fail)
