topic is complicated and might need refinement / edit after some time. but its good to write down my current knowledgebase for future use
OPTION1 ( RPM | Alien )
fedora has rpm installers and GUI is yum (synaptic in ubuntu). often rpm files are needed to installed in ubuntu (maya). process is simple can be done via 2 ways
- install alien package, it converts rpm files to debian files while checking / updating dependencies
- install rpm package, it lets you directly installs rpm files. only negative is it won't appear in add / remove place
installing applications
rpm -ivh --nodeps packagename
query installed apps
rpm -qa | more
removeing apps
rpm -e --nodeps packagename
>> query results x-x-x >> name-version-build>> while removing needs only name
OPTION2 ( APT | dpkg )
ubuntu has debian installers and system that works for auto updating / maintenance is APT, management of debian installers is done by dpkg from terminal and synaptic from GUI
Typing apt-get help will display:
Code:
Usage: apt-get [options] command
apt-get [options] install|remove pkg1 [pkg2 ...]
apt-get [options] source pkg1 [pkg2 ...]
Commands:
update – Retrieve new lists of packages = Reload
upgrade – Perform an upgrade = Default Upgrade
install – Install new packages (pkg is libc6 not libc6.deb)
remove – Remove packages
source – Download source archives
build-dep – Configure build-dependencies for source packages
dist-upgrade – Distribution upgrade, see apt-get(8) = Smart Upgrade
dselect-upgrade – Follow dselect selections
clean – Erase downloaded archive files
autoclean – Erase old downloaded archive files
check – Verify that there are no broken dependencies
