I purged package "libp11-kit-gnome-keyring": $ sudo apt-get purge libp11-kit-gnome-keyring
And wasn't able to reproduce it. I recently removed a lot of packages and there was no broken dependencies. After I got error message when running "avconv -version", I tried reinstalling "libp11-kit-gnome-keyring" because it was mentioned in one of the forums with similar error message when running wine. I didn't fix anything else. I literally ran the command "sudo apt-get install libp11-kit-gnome-keyring && avconv -version" and it didn't show the error anymore. And then I reported the bug. I think that something broke when I was removing a lot of packages (mostly recommended and suggested from other packages), and command "sudo apt-get install libp11-kit-gnome-keyring" fixes that particular something. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to libav in Ubuntu. https://bugs.launchpad.net/bugs/1437447 Title: avconv error "couldn't load module ... gnome-keyring-pkcs11.so" Status in libav package in Ubuntu: Incomplete Bug description: Calling avconv -version prints error: p11-kit: couldn't load module: /usr/lib/x86_64-linux-gnu/pkcs11/gnome- keyring-pkcs11.so: /usr/lib/x86_64-linux-gnu/pkcs11/gnome-keyring- pkcs11.so: cannot open shared object file: No such file or directory Error disappears after installing package "libp11-kit-gnome-keyring", but it is not a dependency of libav-tools.
