Me he encontrado alguna vez con que Chrome soltaba un error diciendo que no podía abrir correctamente mi perfil.

Error: no se ha podido abrir correctamente tu perfil

Resulta bastante molesto ya que te impide acceder a la base de datos de usuarios y contraseñas habituales.

Para verificar el error, podemos ejecutar Google Chrome desde el terminal y podremos ver el siguiente error:

Lo que está ocurriendo es que alguna de las extensiones de Chrome se ha quedado bloqueando la base de datos sqlite que chrome utiliza para almacenar datos de tu perfil. Vamos a solucionarlo.

Entramos al directorio de configuración de google chrome

javi@casa:~$ cd .config/google-chrome/Default/

Ejecutamos el siguiente comando. Este va a identiicar los archivos sqlite almacenados por google en su directorio de configuración, y matar los procesos que estén bloqueando la base de datos.

javi@casa:~/.config/google-chrome/Default$ find . -type f -exec file {} ; | grep -i SQLite | cut -d: -f1 | while read FILE; do fuser -k -TERM "$FILE"; done 
/home/javi/.config/google-chrome/Default/QuotaManager: 3964
/home/javi/.config/google-chrome/Default/Login Data: 3964

Tras esto, Chrome vuelve a abrir sin problemas ni errores de que no puede acceder a nuestro perfil.
