It seems that this is a crash. After force shutdown, restart and enter ubuntu. due to update failure, neither the keyboard nor mouse can be used, and the resolution is very low. Fortunately, the tab key can still be used. The NIC driver is gone and cannot be updated online. Solution: 1: Press the key and press the tab key to restart www.2cto.com 2: Select the recovery mode of the previous version in previous version, and then perform network repair. 3: Restart. select the first option for ubuntu. after entering the option, the network will be ready for use and the software will be updated. Ps: You can perform many operations in the recovery mode, such as clearing the old kernel and releasing space. If a problem occurs in ubuntu, you can enter the previous version or repair mode.
