I always update with dist-upgrade, precisely to avoid missing drivers and other auxiliary files. I haven't experienced problems yet (~5 years of doing this). --Bob. On 14/09/18 11:04 AM, Lennart Sorensen via talk wrote:

What is libGL? Read this: <https://dri.freedesktop.org/wiki/libGL/>
It looks as if ffmpeg is trying to use your graphics card to help with the conversion.
libGL is unable to load a driver. Since one of the later choices appears to be a pure-software driver "swrast_dri", your problem isn't missing hardware.
I'd guess the libgl used by ffmpeg is obsolete and out of sync with /usr/lib64/dri/. Or perhaps you are using a 32-bit ffmpeg on a 64-bit system, or vice versa.
Have a look in /usr/lib64/dri/ and /usr/lib/dri/. Are both populated? For example, on my system, I have: /usr/lib64/dri/swrast_dri.so
Did you install ffmpeg from the ubuntu repositories? If not, it might be out of sync with the other components (like libGL) which do get updates from the ubuntu repositories.
How did you update ubuntu? Sometimes you need to use "apt-get dist-upgrade", not just "upgrade". (I'm not a Ubuntu expert.)
