I execute these commands:
1. apt-get update
2. apt-get dist-upgrade
3. reboot
4. apt-get install -y virtualbox-guest-x11 and finally I reboot again and I get nothing else to make the first command this error:E: Could not open lock file / var / lib / apt / lists / lock - open (13: Permission denied)
E: Unable to lock directory / var / lib / apt / lists /
W: Problem unlinking the file /var/cache/apt/pkgcache.bin - RemoeCaches (13: Permission denied)
W: Problem unlinking the file /var/cache/apt/srcpkgcache.bin - RemoeCaches (13: Permission denied)
I have also tried the commands preceded by "sudo", they run but do not work, even after reboot several times.
If someone can help me or know any way to put a full screen, I'd appreciate it.
