I don't know much about permissions, but check:

Code: Select all

 find $HOME ! -user $USER 

It should come back empty. if not, do:

Code: Select all

 sudo chown -R $USER:$USER $HOME 

Now the first command should return empty.

Thank you very much for your reply.
First command returned with lots of folder , the ones I wasn't able to access.
Second command made the first one returned empty as you said.

Could this trouble have been caused because these were folders that I saved in my partitions and move them arround from one partition to the other, before formatting? .. Anyway the only partition I formatted was / and then did a fresh install. Documents folder used to be encrytped with veracript but I left that program a long time before ago.
I am wondering how this maight have been caused..

Now I can access to those folders without trouble, save files and copy and paste....thank you so much!!!

PS: please tell me what we did?

[sleeper12]

Well, my limited understanding is that those commands restored your permissions. What caused it, I have no clue. Maybe someone else will know. Glad it fixed things though.

I have set my user settings as administrator and also set my user in admin group.

I think this is what caused your problem. I'm not sure so somebody else will have to verify.

[sleeper12]

Schultz, you may have nailed it, but I'm not sure either.

Interestingly I have a few things owned by root.

Code: Select all

$  find $HOME ! -user $USER 
/home/mike/.local/share/applications/bitnami.desktop
/home/mike/.dbus
find: ‘/home/mike/.dbus’: Permission denied
/home/mike/.cache/dconf
find: ‘/home/mike/.cache/dconf’: Permission denied
/home/mike/.cache/at-spi2-socket-23581
/home/mike/.cache/at-spi2-socket-19217
/home/mike/.cache/at-spi2-socket-6520
/home/mike/.cache/at-spi2-socket-25046
/home/mike/.cache/at-spi2-socket-4306
/home/mike/.cache/at-spi2-socket-17174
/home/mike/.cache/at-spi2-socket-11594
/home/mike/.cache/doc
find: ‘/home/mike/.cache/doc’: Permission denied
/home/mike/.cache/at-spi2-socket-5432
/home/mike/.gvfs
find: ‘/home/mike/.gvfs’: Permission denied

Many of those are links (hard links I think).
'bitnami.desktop' is not a link. Neither are the sockets, but they have zero bytes.
I'm not worried about any of this and will probably leave it as-is. But it is interesting.

Oh no, I didthat just to try fixing the problem, before posting this topic.
