Current evaluation

Credential login worked again after updated Windows, WSL2, Ubuntu, Snap, and Snapcraft components; the reporter closed the report as no longer reproducible, with no linked fix.

Resolution: closed stale

Reason: The reporter's September 17, 2024 closing comment said the failure disappeared after updating all components and that there was no value in investigating an unidentified transient. No resolving PR or commit was identified.

Issue body

### Bug Description WSL2 doesn't run with a proper desktop session and must authenticate with the `SNAPCRAFT_STORE_CREDENTIALS` environment variable. This has traditionally worked for years. Having tried recently, this no longer works, Snapcraft will unconditionally complain about lack of system keyring and refuse to consider the environment variable. ### To Reproduce * Install WSL2, Snapcraft snap * Export login-token (`snapcraft export-login $fileName`), export it into the environment variable, and try perform a server-authenticated action. ``` james@James-Desktop:~/pinta-snap$ export SNAPCRAFT_STORE_CREDENTIALS=$(cat ../token) james@James-Desktop:~/pinta-snap$ snapcraft upload pinta_2.1.2_amd64.snap --release=stable snapcraft internal error: NoKeyringError('No keyring found to store or retrieve credentials from.') ``` ### Environment ``` james@James-Desktop:~/pinta-snap$ snapcraft version snapcraft 8.3.2 james@James-Desktop:~/pinta-snap$ snap version snap 2.63+22.04ubuntu0.1 snapd unavailable series 16 Windows Subsystem for Linux - kernel 5.15.153.1-microsoft-standard-WSL2 (amd64) ``` Windows environment: Fully updated Windows 11 22H2 (latest GA release) ### snapcraft.yaml ```shell N/A ``` ### Relevant log output ```shell 2024-08-23 20:06:17.990 Starting snapcraft, version 8.3.2 2024-08-23 20:06:17.990 Log verbosity level set to BRIEF 2024-08-23 20:06:17.990 Configuring application... 2024-08-23 20:06:17.990 Preparing application... 2024-08-23 20:06:17.990 Build plan: platform=None, build_for=None 2024-08-23 20:06:17.991 Running snapcraft upload on host 2024-08-23 20:06:18.013 snapcraft internal error: NoKeyringError('No keyring found to store or retrieve credentials from.') 2024-08-23 20:06:18.015 Traceback (most recent call last): 2024-08-23 20:06:18.015 File "/snap/snapcraft/12378/lib/python3.10/site-packages/craft_application/application.py", line 530, in run 2024-08-23 20:06:18.015 return_code = dispatcher.run() or 0 2024-08-23 20:06:18.015 File "/snap/snapcraft/12378/lib/python3.10/site-packages/craft_cli/dispatcher.py", line 487, in run 2024-08-23 20:06:18.015 return self._loaded_command.run(self._parsed_command_args) 2024-08-23 20:06:18.015 File "/snap/snapcraft/12378/lib/python3.10/site-packages/snapcraft/commands/upload.py", line 114, in run 2024-08-23 20:06:18.015 client = store.StoreClientCLI() 2024-08-23 20:06:18.015 File "/snap/snapcraft/12378/lib/python3.10/site-packages/snapcraft/store/client.py", line 179, in __init__ 2024-08-23 20:06:18.015 self.store_client = get_client(ephemeral=ephemeral) 2024-08-23 20:06:18.015 File "/snap/snapcraft/12378/lib/python3.10/site-packages/snapcraft/store/client.py", line 161, in get_client 2024-08-23 20:06:18.015 client = craft_store.UbuntuOneStoreClient( 2024-08-23 20:06:18.015 File "/snap/snapcraft/12378/lib/python3.10/site-packages/craft_store/ubuntu_one_store_client.py", line 47, in __init__ 2024-08-23 20:06:18.015 super().__init__( 2024-08-23 20:06:18.015 File "/snap/snapcraft/12378/lib/python3.10/site-packages/craft_store/base_client.py", line 77, in __init__ 2024-08-23 20:06:18.015 self._auth = Auth( 2024-08-23 20:06:18.015 File "/snap/snapcraft/12378/lib/python3.10/site-packages/craft_store/auth.py", line 201, in __init__ 2024-08-23 20:06:18.015 raise errors.NoKeyringError 2024-08-23 20:06:18.015 craft_store.errors.NoKeyringError: No keyring found to store or retrieve credentials from. 2024-08-23 20:06:18.015 Full execution log: '/home/james/.local/state/snapcraft/log/snapcraft-20240823-200617.989721.log' ``` ### Additional context _No response_
