When I launch digikam I get an error about a cuda missing library (this is happening since I removed cuda more or less cleanly to solve something else):

hippo@hippo-camp:~$ digikam<BR>
digikam: error while loading shared libraries: libcudart.so.8.0: cannot open shared object file: No such file or directory<BR>
hippo@hippo-camp:~$ which digikam<BR>
/usr/bin/digikam<BR>
hippo@hippo-camp:~$ lddtree /usr/bin/digikam<BR>
digikam => /usr/bin/digikam (interpreter => /lib64/ld-linux-x86-64.so.2)<BR>
-     libdigikamgui.so.5.6.0 => /usr/lib/digikam/libdigikamgui.so.5.6.0<BR>
--        libopencv_core.so.3.2 => /usr/local/lib/libopencv_core.so.3.2      
---             libcudart.so.8.0 => not found

as you can see libcudart is a dependency of opencv. I think it is linked to the face recognition feature which I don't really need.

How can I fix this? is there a way to install just the lib?

I have tried to reinstall cuda from scratch but it only gives me version 9 or 10. And I cannot reinstall version 8 from NVIDIA site because I am now in 18.04.3 LTS and it is only supported on version 16.04.

I have tried --purge and reinstall digikam but it does not fix the problem.

sudo apt-get install libopencv-dev python3-opencv --reinstall

did not solve it neither.

EDIT: the library is not anymore on this machine and I don't have a cuda-8 directory anywhere.

How can I fix this situation?

I would like to know in advance which files would be deleted if I ran apt purge <pkg> and that would not be deleted by running the apt remove <pkg> command.

Is there some CLI voodoo better that running both command with -s and comparing the results?

My ubuntu 16.04 bootime is consistently long (several minutes). When i run

systemd-analyze blame

the first line is

 2min 687ms open-iscsi.service

The box is indeed setup with an iscsi drive (a separate NAS box) but I keep this drive off 99% of the time which could explain the long boot time.

My question is, how do I setup my system so that the unsuccessful wait for the iscsi connexion does not slow down the boot process?

Things I tried:

I tried to setup the replacement_timeout to -1 in /etc/iscsi/iscsid.conf

node.session.timeo.replacement_timeout = -1

but it did not prevent the 2 minutes wait time.

EDIT: additional infos

1/ there is no entry in /etc/fstab for that disk

2/ service status gives some info

I migrated from ubuntu 16.04 to the xfce4-panel 4.12.0 environment as I installed ubuntu-studio.

The menus of an application window ("file", "edit", "option", "tools"...) appear in one of the screen bars when i add the 'indicator' plugin.

I'd rather have those menus in their own windows (where they belong imho). Is there a way to do that with this desktop? in gnome there is the appearance / behavior checkbox that will put the menus in the application window bar, that would be perfect if this existed but i haven't found a way to do the same in xfce.
