Disable repository updating in fedora

Question

Fedora checks all repository for updating when every time i want to install some packages from yum. this is waste of time because i know they are updated!

how could i disable this checking?

Answer 1

if you know yum is updated then before going to install go to

/etc/yum.repos.d directory and edit /etc/yum.repos.d/fedora-updates.repo

and make changes in updates. In updates there is a value enabled set to 1, so change this to 0.

enabled=value

…where value is one of:

0 — Do not include this repository as a package source when performing updates and installs. This is an easy way of quickly turning repositories on and off, which is useful when you desire a single package from a repository that you do not want to enable for updates or installs.

1 — Include this repository as a package source.

Turning repositories on and off can also be performed by passing either the --enablerepo=repo_name or --disablerepo=repo_name option to yum, or through the Add/Remove Software window of the PackageKit utility. 

Answer 2

You can Simply use :

yum --disablerepo=\* --enablerepo=your_repo  install packagename

You can list repo using :

yum repolist

if you want to disable permanent then you have to edit /etc/yum.repos.d/*.repo and disable it manually

Answer 3

The "repo is up to date" check is fast, so it shouldn't be a bother. Going around disabling repositories for the sake of a few seconds will exact bloody revenge later...

If you are worried that yum -y install package-A; yum -y install packge-B; ... will do checking over and over, just do yum -y install package-A package-B ...

BTW, Fedora 18 has the experimental dnf yum replacement, much faster and accurate. It can be installed in paralell. Works like a charm, but still has some rough edges (when it decides that there are unresolvable conflicts, it just finishes silently without doing anything).
