Question

I have installed ubuntu 12.04. There are two users accounts in my system. evince showing problem in one of my user accounts (user5).

(evince:26724): Gtk-WARNING **: Attempting to read the recently used resources file at `/opt/home/user5/.local/share/recently-used.xbel', but the parser failed: Failed to open file '/opt/home/user5/.local/share/recently-used.xbel': Permission denied.

(evince:26724): Gtk-WARNING **: Attempting to store changes into `/opt/home/user5/.local/share/recently-used.xbel', but failed: Failed to create file '/opt/home/user5/.local/share/recently-used.xbel.6OQ9NX': Permission denied

The above mentioned error keep on repeating. I have given permission for recently-used.xbel file, but the problem persists.

Answer 1

It could be AppArmor:

Check /var/log/kern.log for entries like :

May 11 10:17:35 dev kernel: [2336998.770824] type=1400 audit(1431364655.819:726): apparmor="DENIED" operation="chmod" parent=19487 profile="/usr/bin/evince" name="/data/home/fritz/.local/share/recently-used.xbel" pid=23290 comm="evince" requested_mask="w" denied_mask="w" fsuid=1001 ouid=1001

check where your home directory is. If it's a symlink from /data/home -> /home then you need to modify AppArmor to to have the true home directory in it.

sudo vim /etc/apparmor.d/tunables/home

and modify HOMEDIRS accordingly

@{HOMEDIRS}=/home/ /data/home/

then restart apparmor

sudo /etc/init.d/apparmor restart

Answer 2

the message "Gtk-WARNING" to access:

/home/user/.local/share/recently-used.xbel # user is echo $USER

or

/root/user/.local/share/recently-used.xbel # if exist

It is solved like this:

First verify the permissions

ls -l /home/user/.local/share/recently-used.xbel
-rw------- 1 user user 3321 nov 21 08:58 /home/user/.local/share/recently-used.xbel

sudo lsattr /home/user/.local/share/recently-used.xbel
--------------e--- /home/user/.local/share/recently-used.xbel

If the result is not described above. For example:

-rw------- 1 root root 3321 nov 21 08:58 /home/user/.local/share/recently-used.xbel
-----i--------e--- /home/user/.local/share/recently-used.xbel

Fix it like this:

sudo chattr -i /home/user/.local/share/recently-used.xbel
sudo chown user:user /home/user/.local/share/recently-used.xbel

Note: For security reasons it is better to remove it
