Ketika saya mencoba menginstal "ubuntu dibatasi ekstra" di "pusat perangkat lunak ubuntu", itu akan menampilkan dialog peringatan yang mengatakan item berikut harus dihapus:
libavcodec53
libavutil51
Mengapa? Dan jika saya memilih untuk menginstal "ekstra terbatas ubuntu", apa yang akan saya hilangkan?
PS: Saya rasa saya melihat libavcodec53 melewati flash ketika paket codeblock harian saya sedang diinstal ... jadi itu satu kemungkinan. Apakah saya akan memecah lingkungan pengembangan perangkat lunak saya jika saya menginstal "ubuntu dibatasi ekstra"?
Atau apakah paket-paket ini perlu dihapus karena mereka termasuk dalam "ubuntu dibatasi tambahan"? Jika demikian, mengapa dialog tidak menyebutkan itu (dan menghilangkan kekhawatiran dan kebingungan)?
PS: Output yang dihasilkan oleh apt-get -s install ubuntu-restricted-extras

NOTE: This is only a simulation!
apt-get needs root privileges for real execution.
Keep also in mind that locking is deactivated,
so don't depend on the relevance to the real current situation!
