Boris,

You do not need to use sudo when you are root.

Also, you could have tested easily by manually moving or copying the config file in your original post as root.

Thanks Neo,
I tried sudoedit, gedit etc but none of them worked.
It was saying read only. Also rm command was not responding..
I suppose after upgrading from ubuntu14.04 to 16.04, I broke my repositories and made some non-returnable changes so that the system could not have repaired it. I am not a professeur on linux :/ You all may guess what could be the solution.

Thank you
Boris

If you are root and cannot perform simple operations like move, copy and edit you need to check your filesystem to insure it is not mounted read only.

There is one more thing that could be an issue, denying deletion ever for root.

Check in the working directory with command lsattr /etc/mysql
The former admin perhaps implemented immutable flag with chattr +i <file>

Until that flag is removed with chattr -i <file>, you won't be able to do much with file except reading it.

Very underused and forgotten feature.

Example :
Code:
root@hickup:~/example# pwd
/root/example
root@hickup:~/example# printf "%s\n" "some text" > example.conf
root@hickup:~/example# chattr +i example.conf 
root@hickup:~/example# lsattr example.conf 
----i---------e---- example.conf
root@hickup:~/example# rm example.conf 
rm: cannot remove 'example.conf': Operation not permitted
root@hickup:~/example# rm -f example.conf 
rm: cannot remove 'example.conf': Operation not permitted
root@hickup:~/example# printf "%s\n" "Add text" >> example.conf 
-bash: example.conf: Operation not permitted
root@hickup:~/example# mv example.conf example2.conf
mv: cannot move 'example.conf' to 'example2.conf': Operation not permitted

Hope that helps
Regards
Peasant.

Before setting with chattr , the OP should probably list first, for example:

Code:
lsattr example.conf

The OP said he does not have any experience in Linux, so before going around changing file attributes, he should list them first before he makes even more mistakes.

My first guess is the the file system has been mounted read-only.
