If during a refresh you encounter an error like "Failed to create logfile...permission denied" then you need to edit your config file to have the correct file paths. All file paths in the config file should use the /current/ snap install not a specific version number. You can also remove and re-install the Grin Snap but this will require a re-sync.
This is a convenient command you can run to perform the fix.
sed -i 's/grin\/[0-9]\/.grin/grin\/current\/.grin/g' ~/snap/grin/current/.grin/main/grin-*.toml
Warning - Use of Grin via Snap install may reduce your privacy due to tracking of IP address and usage patterns.
Grin is a privacy-preserving digital currency built openly by developers distributed all over the world. It can be used by anyone, anywhere, without restriction or censorship.
Grin implements the Mimblewimble protocol and as such has no public amounts or addresses. Transactions are aggregated which makes efficient use of storage space. In order to conceal their origin, newly created transactions are relayed among a sub-set of peers before being widely broadcast.
Grin is not controlled by any company, foundation or individual. The coin distribution is designed to be as fair as possible, with an emission of 1 GRIN per second.
Mimblewimble leverages cryptography to allow past transaction data to be removed with no compromise on security. This avoids Grin collapsing under the weight of data having to be kept on chain.
This Snap contains two applications:
grin - The blockchain node software which can be started with default settings just by typing grin in your terminal.
grin.wallet - For creating a new account, sending and receiving transactions. Run grin.wallet help to see a list of available commands.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap is available for CentOS 7.6+, and Red Hat Enterprise Linux 7.6+, from the Extra Packages for Enterprise Linux (EPEL) repository. The EPEL repository can be added to your system with the following command:
sudo yum install epel-release
Snap can now be installed as follows:
sudo yum install snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install Grin, simply use the following command:
sudo snap install grin
Browse and find snaps from the convenience of your desktop using the snap store snap.
