We switched the base image of Symbolicator, it now runs as user 65532 by default. You should be able to chown the files to that user or simply re-create the volume (it's just caches).

@aldy505 anything we can do for the release to make this automatic?

Options:

• Run symbolicator with the old user (can just override the user via docker)
• Re-create the volume automatically (or maybe just use a new volume?)
• Automatically chown to the new user
• Manual upgrade step

@Dav1dde Which volume does it use?

[Dav1dde]

sentry-symbolicator:

self-hosted/docker-compose.yml

Lines 830 to 831 in 5cf07c8

	external: true

@Dav1dde So the solution could be simply delete the volume as it only contains temp cache data?
