Hi, I'm having a problem updating, when I run the command "apt-get update"
The following problem returns me:Downloaded 5,609 kB in 7s (781 kB / s)
W: There are no public keys for the following key IDs:
EF0F382A1A7B6500
W: Failed to fetch http://www.deb-multimedia.org/dists/stable/InRelease Unable to find the expected 'main / binary-powerpc / Packages' entry in the Release file (wrong entry in sources.list or malformed file )
E: Some index files failed to download. They were ignored or the old ones were used instead.
Please tell me I am looking forward to using Debian 9.
Which safer update command?
Apt-get dist-upgrade?
or
Apt full-upgrade?
