Briefly describe your issue below:
What version of Parrot are you running? (include version (e.g. 4.6), edition(e.g. Home//KDE/OVA, etc.), and architecture (currently we only support amd64)
Mate
What method did you use to install Parrot? (Debian Standard / Debian GTK / parrot-experimental)
Debian Standard
Configured to multiboot with other systems? (yes / no)
No
Ok, after installing my os ( parrot sec 4.9.1 ), I did sudo parrot-upgrade, and it said 1,753 are to get downgraded, some 157 to be upgraded and 38 to removed, and it took 2.8 gb of data to get upgrade.
So, after update and upgrade, everything programme in the system aren’t working, so I shocked and rebooted the system, then my pc boots upto grub and shows to choose the os what I need and then the following os shows parrot os symbol and then it loads, then it becomes black screen.
I have tried every other options in grub and everything loads into the first parrot os loading page and struck with black screen.
Please fix this issue.
