unable to os-compose tree on fedora 21 - fedora

Waiting for yum...
One of the configured repositories failed (Fedora 21 - x86_64),
and yum doesn't have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work "fix" this:
1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).
3. Disable the repository, so yum won't use it by default. Yum will then
just ignore the repository until you permanently enable it again or use
--enablerepo for temporary usage:
yum-config-manager --disable fedora-21
4. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:
yum-config-manager --save --setopt=fedora-21.skip_if_unavailable=true
Cannot retrieve metalink for repository: fedora-21/x86_64. Please verify its path and try again

Update package installed from git in Yarn 3

How to update a proprietary dependency installed from Git repo with Yarn 3?
package.json entry:
"#foo/utils": "git+https://gitlab+deploy-token-...:...#gitlab.com/foo/bar.git#ISSUE-6652-some-git-branch",
yarn up #foo/utils results in the following error:
➤ YN0027: #foo/utils#git+https://gitlab+deploy-token-...:...#gitlab.com/foo/bar.git#ISSUE-6652-some-git-branch can't be resolved to a satisfying range
Internal Error: The remote server failed to provide the requested resource
I need to update the package to latest commit in that branch and the only way I currently know is removing entry for this package manually from yarn.lock, but I guess that's not how things should be done.
It's not ideal since it's interactive, but you can run yarn up -i #foo/utils and choose "reuse" to force the package to resolve (and reinstall) from the same git source again.

Fedora updates - via dnf or gnome-software?

I'm running Fedora Workstation 22 on my Notebook. After installing it, I've done
dnf upgrade
to update all packages (was around 700 MB) - and checked the Gnome-Software applications for Updates. Gnome Software hasn't offered any updates. But sometimes, I get a notification from Gnome software to restart my Computer and install the Updates.
I found this procedure - Offline updating for libraries and components which are currently running - in the Wiki. But I don't understand how this works. If I install dnf upgrade, didn't this command update all packages to the most current version in the repos? Is Gnome-Software using different repositories, or how does this mechanism work?
I wanted to update my entire system via command-line. How can I do than? I'm a bit confused, because - for example - on Debian I could simply type
apt-get update && apt-get upgrade
to update my entire system. How is this possible in Fedora?
Its pretty much easy to update your fedora 22.
Use this command and it will simply update your fedora 22 with all available packages.
sudo dnf update
and if you are already root, simply use
dnf update
and will update your fedora.
For any other query related to update, write it in comments.

Error using YUM and DNF in Fedora 21

I read this article in fedoramagzine.org and followed the process. Since then I am unable to perform updates, installation etc from both yum and dnf.
This is the error I get from DNF
Abhinav#localhost ~$ sudo dnf update
[sudo] password for Abhinav:
Error: Failed to synchronize cache for repo 'fedora' from

and this is the error I get when using YUM

I even emptied all the repos in /etc/yum.repos.d except for the original 3 repos you get when you install distro.

UPDATE 2
Formatted my laptop and re-installed Fedora 21. After 3 sudo dnf updates. I am stuck with this problem again. This time i didn't follow the steps on the previous article.
On further google search I found https://fedorahosted.org/fedora-infrastructure/ticket/4517 which talks about same error. It is closed but I can't find a proper solution again.
If you sit behind a proxy, you have to configure dnf accordingly. (Even if the user's proxy settings are fine, you have to set them for dnf anyway.) The dnf settings are stored in /etc/dnf/dnf.conf. The syntax is:
proxy=<protocol>://<ip or name>:<port>
If this is not your problem, try to download the metadata with the browser to ensure, that your network connection to the url is working.
The file to receive should be an xml file. If you cannot download the metadata via the browser, chances are, that either port 443 (for https) is blocked or there is something wrong with your internet connection.

While logged into fedora23VM , running yum update in verbose mode
sudo yum --verbose update a curl timeout on downloading from each of the repository presented in the metalink.
e.g
error: Curl error (56): Failure when receiving data from the peer for http://ftp.polytechnic.edu.na/pub/fedora/linux/updates/23/x86_64/repodata/af3c46471b1d685f22c72a5e16d7383d333fb89db278711b2b8c794e29a91eaa-filelists.xml.gz [Recv failure: Connection reset by peer] (http://ftp.polytechnic.edu.na/pub/fedora/linux/updates/23/x86_64/repodata/af3c46471b1d685f22c72a5e16d7383d333fb89db278711b2b8c794e29a91eaa-filelists.xml.gz).

i.e
curl -k -O https://www.ftp.saix.net/linux/distributions/fedora/linux/updates/23/x86_64/repodata/repomd.xml
Solution
Disable ssl certificate verification during the yum update i.e
sudo yum --verbose update --setopt "sslverify=0" -y

"Yum Update" reinstalling removed packages

On my Fedora 19 system, yum update attempts to reinstall a large number packages I have previously removed. This should not happen, as the packages listed are not installed and should not be suggested by yum. How can I make yum work in the expected manner - with updates suggesting only upgrades to preinstalled packages.
Background: I have been trying out new DEs - installing and removing them as I go. Currently, I'm in a DE-less state, booting directly into a tty terminal. My system has no (or a few hidden) xfce or cinnamon packages to "upgrade", yet the package manager is suggesting 300 packages to install, totaling 600M of new install.
Terminal output gist:
https://gist.github.com/Redoubts/29400f0b98cd13120a6a#file-gistfile1-txt
Short answer - It's not possible to disallow installing any packages from the depenency chain. Either you install all of them or drop those who depends on unwanted packages.
In some cases, when the package from a dependency chain is required only during some specific stages of installation (say for execution of a pre- or post-install scripts), it's possible to remove thise package later, after the complete installation. But that's not what you want I suppose.

What is a yum package conflict?

When running the transaction check to install mysql i'm getting:
Processing Conflict: mysql55-5.5.29-1.w6.x86_64 conflicts mysql < 5.5
I guess this means i'm attempting to install a package called mysql55-5.5.29-1.w6.x86_64 on to a system with mysql already installed but somehow there is a conflict?
yum says that mysql isn't installed so it was installed without using the repositories. In that case how does yum know there is confict?
it would be good to better under what 'confict' means.
There are many online yum repo available and all are free opensource contribute. So source packages are compiled with different options in each repo. So when we add 2 or more yum repo at a time, it may happen that 2 or more packages are of same version are selected and we get a conflict error.
In your case you added some repo which is providing mysql 5.5 which is already available with some other name in some other repo or already installed but new mysql package is selected by yum for any other package as dependency. Try removing one of the repo or try installing it as yum install mysql-5.5*
You can try this : yum list | grep mysql. It will list mysql in different packages, then you can make a decision to remove one of them and install mysql again.
