Hello, I am a linux newby and having tasted the goodies of Fedora 9, I am now a very convinced linux wannabe.

The sense of control in the type and execute is, to tell the tale , a great ride and having found just what a chum yum could be, I yummed a lot of installs – yum presto too.

Since I found yum Presto is too pronto in its execution and does not really update effectively, to get rid of this part of the otherwise most excellent yum , as root I executed the command :-
“yum erase yum presto”

Yum erased a lot of stuff more and beyond yum presto.

Now if I execute any “yum” command such as “yum update”, the terminal returns the message:-

bash: yum: command not found

Please help me out of this mess

I'm afraid you've uninstalled yum. yum erase yum-presto would have done what you want, but with a space instead of a hyphen, yum saw two things to remove: yum itself and "presto" (which doesn't exist - the package's name is yum-presto). The power of the command line is great, as you say, but it can be dangerous!

At this point, the quickest thing to do might be to reinstall Fedora. But before you "go nuclear", we can have a go at reinstalling yum. You can download the package directly from here:
http://download.fedora.redhat.com/pu...fc9.noarch.rpm

But pick the correct architecture for your system (post the output of uname -i if you're not sure) - that's the i386 version.

That file is what yum would download if it were installing the package automatically, but you can install it yourself with
This is an older way of installing things. The disadvantage is that rpm can't go online and find other packages that yum depends on (that's what's so great about yum and other package managers), so you may get a "failed dependency" error if yum also erased other packages on which it depended. With a bit of patience you should be able to sort it out though, all the dependencies will also be available as rpm files from the URL above. If you get a failed dependency error, just keep installing the required packages until you can install yum!

Hope that's clear, post the output of the rpm command if you can't get it to work.


PS: there are a lot of other packages whose names begin with "yum" that you'll also have erased. Once you've got yum installed, you probably want to install those too. The ones on my system (F8) are:
yum-fedorafaq
yum-metadata-parser
yum-priorities
yum-updatesd
yum-utils

and AFAICR all of those were installed by default when I installed Fedora, except possibly yum-priorities.

Just grab a yum rpm package from any of the Fedora mirrors (this one, for example) and install it with..It's possible that rpm will complain about missing dependancies - if it does (I'm not sure if yum depends on any other packages apart from rpm and wget/curl which it uses for downloading and installing) you'll also have to pull those missing rpm packages from the mirror and install them via rpm -ivh just like above.

I hope this is clear.

Many thanks for the detailed suggestion and the earnest mind behind your suggestion and thank you too "Maligree"

So I clicked on the link that you had provided and downloaded the package and then executed the suggested command.

The terminal replies as follows:-

"error: open of yum-3.2.14-10.fc9.noarch.rpm failed ; No such file or directory"

Have I indeed done precisely that you have so kindly suggested? Is there
any thing else to try, before I commit harakiri?!

Thanks again and my best regards

The rpm command has to be issued in the directory which contains the .rpm file (or you have to give the full path to the file).

Also, please confirm that the output of uname -i is i386 before installing the file.

My suspicion - You're in the wrong directory. (Been there several times myself!)

When you downloaded the package, where did you save it? Make sure you are in that directory before running rpm.

You can also run rpm -ivh http://mirrors.usu.edu/fedora/linux/...fc9.noarch.rpm

To:- John In France - Thanks.
1. the file was downloaded by the browser to home/downloads.
2. how do I go to that directory to run rpm from there?

To:-Battle Roll - I ran the rpm command you suggested :-

the terminal replies "skipped download - unknown error

cd downloads from your home directory, or cd ~/downloads from anywhere. pwd will tell you your current directory, ls will list the files in the current directory. Remember when you type the rpm command that file names are case-sensitive (don't use capitals unless they're there in the filename).

To Opensauce

Both sugggestions in the terminal as "root" return "no such file or directory"

Now I seem to be really "firefoxed"!!!

You have a knack for finding just the right way to prevent our suggestions from working . Not blaming you (or me or the others), it's just that bash (the shell program which is interpreting your commands) is complex, and when you're used to it it's hard to think of every little step to guide a newbie through it.

The ~ character expands to the home directory of the current user. So cd ~/downloads will work when you're logged in as yourself, but if you're logged in as root then ~ expands to root's home - not where you want to be. The actual path to your home dir is /home/yourusername, so you can use that instead of ~ when you're logged in as root. By the way, remember that file names are case-sensitive - are you sure it's downloads and not Downloads?

You might want to google around for a tutorial on the basics of bash - this one looks alright. If you're having trouble finding files and directories, use pwd to find out where you are and ls to see what files are in the current directory. Depending on your distro, subdirectories will hopefully come up in a different colour from regular files so you can see which ones you can cd into. If there's no colour, use ls --color=auto.

What's the output of uname -i please?

I guess opensauce missed the Caps in downloads,

try
see if the file you downloaded is there, then do a
or whatever the filename is.

Please paste in the errors that you get, so that we understand the exact problem and provide a better solution.

Thank you and all of you,

OpenSauce U done cooked my goose!!!

Senior Memeber - i dare'nt attempt a write of your name!

I will take the suggestion of looking up the suggested tutorial and the the other options.

Really appreciate your kind gesture - all of you

P.S:- (I hope it won't be a case of "lost for ever" beyond 48)

-------------------------------------------------------------------------

Having sought the light of TUTs as suggested so kindly by OPENSAUCE, and one what the SeniorMemeber suggested, the terminal replies:- error: can't create transaction lock on /var/lib/rpm/_db.000

What next folks?

I don't know what that means, but I hope it's nothing bad!



That means you haven't told us the output of uname -i
