Wrong path to .gpg file

[Kyrylo Sypko]

I'm using Package version/build 3.1.0-10901-g.f1f8f1505

I try to sync images from maas.io but get an error:

 maasserver.bootresources: [critical] Importing boot resources failed.
        Traceback (most recent call last):
          File "/usr/lib/python3.8/threading.py", line 870, in run

        builtins.FileNotFoundError: [Errno 2] No such file or directory: '/snap/maas/current/usr/share/keyrings/ubuntu-cloudimage-keyring.gpg'

It looks like wrong path for Package version of maas.

To workaround it I just created dir /snap/maas/current/usr/share/keyrings/ and copy /usr/share/keyrings/ubuntu-cloudimage-keyring.gpg there.

Hi Kyrylo,

May I ask you to check if this bug is still reproducible in newer MAAS versions (3.4, 3.5)

It seems that default location is `/usr/share/keyrings/ubuntu-cloudimage-keyring.gpg` if MAAS_IMAGES_KEYRING_FILEPATH is not set. Could it be that you had this ENV set to some value?

# Default images keyring filepath can be overridden by the environment.
DEFAULT_KEYRINGS_PATH = os.getenv(
    "MAAS_IMAGES_KEYRING_FILEPATH",
    "/usr/share/keyrings/ubuntu-cloudimage-keyring.gpg",
)

I installed 3 new .deb maas 3.5 region+rack controllers and removed my 3 older snap ones and faced this.

Workaround:
maas-region dbshell
UPDATE maasserver_bootsource SET keyring_filename='/usr/share/keyrings/ubuntu-cloudimage-keyring.gpg' WHERE id=1;
