I want to write a simple ASIO program for Ubuntu Touch using C++, but I am currently facing difficulties and unable to use apt:
phablet@ubuntu-phablet :/$ sudo apt update
Reading package list complete
E: The directory/var/lib/app/lists/partial for the software package list is missing- Acquire (30: Read-only file system)
What should I do?
