Error:failed to get canonical path of /cow
solution
use the recovery software boot-repair(after installing the Chinese system, look for “boot repair” in Dash) :
we need to use the system CD or U disk to enter the system, and then click “Try Ubuntu”
to install boot-repair, you need to add Ubuntu’s boot-repair PPA source and update the apt library.
sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update
Cannot add PPA if the error is reported… , can see: https://blog.csdn.net/weixin_44436677/article/details/107133371
below is the installation:
sudo apt-get install -y boot-repair
use boot-repair to repair:
use boot-repair on the command line or click open in Dash, and then fix automatically in the software window or select advanced mode to set accordingly.
, wait a little, and restart.
