Trouble shooting

missing go.sum entry for module providing package ...
run go build -mod=mod will generate go.sum
panic: failed to spawn ephemeral node: no IPFS repo found in /home/zhh/.ipfs.
please install go-ipfs and run: 'ipfs init'.
failed to spawn ephemeral node: failed to init ephemeral node: unknown datastore type: flatfs
run ipfs init first
failed to spawn ephemeral node: no version file found, please run 0-to-1 migration tool.
See https://github.com/ipfs/fs-repo-migrations/blob/master/run.md
Sorry for the inconvenience. In the future, these will run automatically.
not init repo directory correctly. run ipfs init first.
failed to sufficiently increase receive buffer size
run sudo sysctl -w net.core.rmem_max=2500000, This command would increase the maximum receive buffer size to roughly 2.5 MB
