Symptoms

• When logging in to Plesk or browsing pages in Plesk, one of the following error messages appears:

Type: SWKeyExFatalError
Message: error: Cannot open file: /etc/sw/keys/info
Type GraphQL Error
Message Internal server error
Type: SWKeyExFatalError
Message: error: Cannot create: /etc/sw/keys/lock/repository: Permission denied

• Plesk license installation fails with:

mkstemp failed: /etc/sw/keys/keys/keyXXXXXX: Permission denied (Error code: 2)

Cause
Permissions on the directory /etc/sw/keys or its subdirectories are incorrect.

Resolution
1.Connect to the Plesk server via SSH.

2.Fix permissions with this command:

#/usr/sbin/usermod -a -G swkey-data psaadm && chown -R root:swkey-data /etc/sw/keys/ && chmod -R 660 /etc/sw/keys/* && chmod -R 644 /etc/sw/keys/info && find /etc/sw/keys -type d -exec chmod 2770 {} \; && chmod 4510 /etc/sw/keys/restart/* && chown -R psaadm:swkey-data /etc/sw/keys/registry.xml /etc/sw/keys/keys/*
3.Restart the Plesk services:

#service sw-engine restart && service sw-cp-server restart
4.Retrieve the Plesk license:

#plesk bin license --retrieve
If the retrieval operation fails, log in to Plesk and install your Plesk license by clicking Install Key.
