They are the same.
apt-get and install are obligatory. The -f is optional and can be placed anywhere after apt-get. Though the man page has them explained as apt-get -f install:
apt-get [-asqdyfmubV] [-o=config_string] [-c=config_file]
[-t=target_release] [-a=architecture] {update | upgrade |
dselect-upgrade | dist-upgrade |
install pkg [{=pkg_version_number | /target_release}]... |
remove pkg... | purge pkg... |
source pkg [{=pkg_version_number | /target_release}]... |
build-dep pkg [{=pkg_version_number | /target_release}]... |
download pkg [{=pkg_version_number | /target_release}]... |
check | clean | autoclean | autoremove | {-v | --version} |
{-h | --help}}
Not much. apt is a new command that supposed to merge several functions from apt-get and apt-cache into one command. It's still a little rough around the edges but here's the command listing from --help:
Basic commands:
list - list packages based on package names
search - search in package descriptions
show - show package details
update - update list of available packages
install - install packages
remove - remove packages
upgrade - upgrade the system by installing/upgrading packages
full-upgrade - upgrade the system by removing/installing/upgrading packages
edit-sources - edit the source information file
The equivalent functions are designed to work in similar ways but it's not a proxy command (it's not calling the old ones - it's a new interface directly onto the Apt libraries) so there may be some edge-case changes.
There are also some obvious omissions (download, policy, etc) that power-users will miss and there are a whole raft of undocumented commands (purge still works but I can't find anything on it).
16.04 Update: A lot of the omissions have now been included but aren't yet documented, nor do they have Bash-completions. It's a shame it's taking this long to implement functionality that already exists in the codebase but oh well. My advice is that if you're used to an apt-{get,cache} command, try it on apt. It might work.
There's also a DIFFERENCES TO APT-GET(8) section in the man apt page that's interesting:
The apt command is meant to be pleasant for end users and does
not need to be backward compatible like apt-get(8). Therefore
some options are different:
· The option DPkgPM::Progress-Fancy is enabled.
· The option APT::Color is enabled.
· A new list command is available similar to dpkg --list.
· The option upgrade has --with-new-pkgs enabled by default.
And if you want Bash-completions, I've had an attempt as writing a completions file for it already. These are included with later Ubuntu installs.

Just tried this minus (or dash) sign after a package and yes , apt-get acting like
remove.Funny thing is I didn't know this function of
apt-get. This minus sign is valid for every package . I tried withsmplayer-withfirefox-and always acting likeremove. So the only thing I can think is that the dash sign at the end of a package considered byapt-getlike a minus andinstallcommand converted toremove.If you wanted to install everything about python3 , then you had to add an asterisk sign after this dash(minus) sign
sudo apt-get install python3-*In the begin I thought this was just a conflict issue , but is not. Sometimes when you install some package and conflict with an other package then the already installed package will be removed due to new installed package , but this is not our situation here.
We've learned something useful today.
From the man-page of apt-get . To read the man-page via your terminal give
man apt-getEventually is not a new option or something weird , is just we don't read the man-pages carefully.
