Unexplained Errors When Starting Kate to Edit GRUB Menu

[mhumm2]

In a previous thread, I learned how to edit the grub config file. When I did so, I received the following:

mark@Mark-AMD64:~$ sudo kate /etc/default/grub
[sudo] password for mark:

Yes, my user name is "mark" and I am in the adm group and my uid is 1000, and my gid is 1000. So what's up with all the errors? BTW, Kate booted just fine and I was able to edit the grub config file and save it without incident. Please advise.

You shouldn't use sudo with gui applications. Use kdesudo instead.
