I am a real newbie. I have Kubuntu 18.04 dual booted with windows 10. They both access files in a separate drive to the OS's. All was working fine for several weeks. Now when in Kubuntu all is fine except when I try to save edited files from any program (including LIbreOffice I get: "Object not accessible. The object cannot be accessed due to insufficient user rights." In Windows all is still fine but my objective is to say goodbye to it. I cannot think of anything that could have caused this. I have checked using Windows that it considers all drives healthy following advice in a similar question.

    A Windows update may have reenabled Windows fast-startup. – mook765 Aug 30 '19 at 23:59

    Please show us your disks setup : edit your question to add the output of this comand lsblk -fm -e 7,11,252 – cmak.fr Aug 31 '19 at 0:10
  • Thanks @mook765 that has cured the problem – Raisalaugh Aug 31 '19 at 2:07

If you are modifying a word document from the windows drive that would be a bit tricky.

Windows likes to keep it's grubby fingers in the pie, ESPECIALY if you have fast boot on. I would turn fast startup off,


If that's not the case, I would check your systems file permissions, make sure you didn't accidently bork your permissions.

A little script I wrote to help with web server permissions. you would copy it into a text file, save the file as "perm.sh" in the command line run

chmod +x perm.sh

and then run it


for i in /* ; do
igno=("/dev" "/sys" "/proc" "/tmp" "/mnt" "/media");

subdir=$(find $i -type d);

if [[ $(echo "$i") != $(echo $igno) ]]; then

printf "\n\n$i has the following stats:\n\n" ;
printf "\n_______________________________________\n\n" ;
stat -c "%n  %a %G:%U"  $subdir | tail -15 | head -14;
printf "\n\n______________________________________\n" ;

I wouldn't post those results here, but just review them, if something doesn't look right, ask.

I love teaching people about linux if you ever need a hand or just wanna chat about linux, drop me a line!
