ok, I reflash and it was the same, so I downgrade to 2.8.1 and from pineapple bar I can see the list of Available Infusions. But when I try to install package I got error:
Sorry, there was an MD5 missmatch. Please try again
I reboot the pineapple, but there was the same error. So, I ssh to pineapple and I cd /usb/ and I menaged to create a file so everything was ok, but when I try to install with "opkg install --dest usb sslstrip" I got this error:
Collected errors: * opkg_install_pkg: Package sslstrip md5sum mismatch. Either the opkg or the package index are corrupt. Try 'opkg update'. * opkg_install_cmd: Cannot install package sslstrip.
So, I update opkg, but there was the same error. From gui in resources, disk usage, I can see usb
/dev/sda1 2.8G 106.3M 2.5G 4% /usb
So ? :(
