I just installed ubuntu 18.04 and I wannted to use opera, so I download it form the website as .deb packages, install and lunch it .
at the very begining everything works fine but when i tryed to login to my account "make synchronization you know" I have this error :
'Can't open user profile directory, because you lack sufficient privileges. You might want to contact the administrator of this machine.'
I couldn't run opera after at all.
