Errors in Ubuntu 18.04 on Windows 10

[Patricia.Guenot]

Hello,


I tried to migrate from WSL Ubuntu 16.04 to Ubuntu 18.04 but it did'nt work.

Then I tried to uninstall Ubuntu 16.04 but I got error 0x80070002


I finally succedeed in installing Ubuntu 18.04 but

I couldn't choose the same username as before, the majuscule in first position caused an error

adduser: Please enter a username matching the regular expression configured
via the NAME_REGEX[_SYSTEM} configuration variable. Use the `--force-badname'
option to relax this check or reconfigure NAME_REGEX.


Now, I have errors in Ubuntu 18.04.


Example :

command sudo apt-get upgrade
