[SOLVED] RPi1 upgrade error today.

[Skywatch]

All other packages upgraded successfully, but not these two....

Code:

The following packages have unmet dependencies:
cec-utils : Depends: libcec2 (= 2.1.4-2)
libcec-dev : Depends: libcec2 (= 2.1.4-2)

[Nachteule]

Remove complained cec packages with

Terminal

sudo dpkg -r --force-all cec-utils
sudo dpkg -r --force-all libcec-dev

and then run

Terminal

sudo apt-get install -f

AFAIR was already here on the forum (or perhaps on github)

[Skywatch]

A search on here for libcec unmet came back with nothing found.

I guess that it is not safe to do that?

[Nachteule]

Hmmm, not really

Next try:

remove all cec packages ( dpkg -r --force-all ) and reinstall libcec. This should install 4 packages

[Skywatch]

Thanks for your support.

That command, should it have cec in it somewhere? Or just as you wrote?

(sorry, I am getting a little paranoid now as 2 pi units both seemed to fail simulatneously today and have spent the evening reflashing, configuring and updating/upgrading again).

[Nachteule]

Hmmm, ok:

Terminal

sudo dpkg -l | grep cec
ii cec-utils 3.0.1-1~xbian-1453441848 armhf libCEC communication Library (utility programs)
ii libcec 3.0.1-1~xbian-1453441848 armhf Meta package libCEC.
ii libcec-dev 3.0.1-1~xbian-1453441848 armhf libCEC communication Library (development files)
ii libcec3:armhf 3.0.1-1~xbian-1453441848 armhf libCEC communication Library (shared library)
ii python-libcec 3.0.1-1~xbian-1453441848 armhf Python bindings for libCEC

That gives you the installed cec packages

And then remove all packages, in my case

Terminal

sudo dpkg -r --force-all cec-utils
sudo dpkg -r --force-all libcec
sudo dpkg -r --force-all libcec-dev
sudo dpkg -r --force-all libcec3:armhf
sudo dpkg -r --force-all python-libcec

And finally

Terminal

sudo install libcec

should install all cec packages again

[Skywatch]

OK, so now I get this...

Terminal

xbian@lounge ~ $ sudo install libcec
install: missing destination file operand after ‘libcec’
Try 'install --help' for more information.
xbian@lounge ~ $ sudo apt-get install libcec

Also, just tried to go back and double check and get the following.....

Terminal

xbian@lounge ~ $ sudo dpkg -l | grep cec
rc libcec3:armhf 3.0.1-1~xbian-1453441848 armhf libCEC communication Library (shared library)
rc xbian-package-cec 9.2.2.0-1-1436247112 armhf libcec 2.2.0 for XBian (rpi/master)

How did I get into this mess in the first place? Was it something I did? Can I avoid it in the future?

[Nachteule]

Did you do a sudo apt-get update?

please run

Terminal

sudo apt-cache search libcec
libcec2 - USB CEC Adaptor communication Library (shared library)
cec-utils - libCEC communication Library (utility programs)
libcec - Meta package libCEC.
libcec-dev - libCEC communication Library (development files)
libcec3 - libCEC communication Library (shared library)
python-libcec - Python bindings for libCEC

Seems your /etc/apt/sources.list.d/xbian.list is broken

No, you never said to do that

Terminal

libcec-dev - USB CEC Adaptor communication Library (development files)

xbian@lounge ~ $

I Have....

Terminal

deb mirror://apt.xbian.org/mirror.txt stable main rpi-jessie
deb mirror://apt.xbian.org/mirror.txt staging main rpi-jessie
##deb mirror://apt.xbian.org/mirror.txt devel main rpi-jessie

Are you normally up this late?

Quote:Well that *is* weird, the file is totally blank. Nothing.

Ok, now we have the explanation for that strange behavior

Quote:I'll repopulate it and see how it goes. Are you normally up this late?

Nachteule == Nightowl (you understand)

[Skywatch]

I updated my post above. I left out the /etc/ at the start, getting late I suppose. Anyway the apt list is OK.

Anyway, I will let you fly now as I need my sleep!

[Nachteule]

Ok, good night

Maybe a mirror is broken, you could try (for testing) http://apt.xbian.org instead of mirror://apt.xbian.org/mirror.txt in file xbian.list

[Skywatch]

OK, I modified the mirror and still the same happens....

xbian@lounge ~ $

---

OK - I have this sorted now! Phew!

From memory the process was.....

Change the mirror
apt-get clean
apt-get update
apt-get -f install
apt-get update
apt-get upgrade (from xbian-config)

Now all packages are back to the latest versions.

What could have caused this and can I prevent it in the future?

[Nachteule]

Quote:What could have caused this and can I prevent it in the future?

Maybe some serious error(s)/warning(s) ignored? Bad mirror? Or simply shit happens ...

Impossible to say ...

[Skywatch]

Probably the last one

Thanks for the support on getting this sorted out though, I really appreciate it!
