Hi,

"dnf upgrade" command returning a error message:

Error: Failed to synchronize cache for repo 'updates' :confused:

kindly help me !!!!

Thanks in advance.

Check if the repositories are updated with the command

dnf repolist

[papai]

Thanks for your suggestion.

in reply to "dnf repolist" command, I am getting the same error: "Error: Failed to synchronize cache for repo 'updates' "

again seek help !!!

try

dnf clean all
dnf distro-sync

[papai]

dnf distro-sync output:

Error: Failed to synchronize cache for repo 'updates'

still not solved....!

Did you do the 'dnf clean all' prior to your 'dnf distro-sync'?

[papai]

yes.
1st : 'dnf clean all'
2nd: 'dnf distro-sync'

but getting same error....!

[antikythera]

in that case open the repository file /etc/yum.repos.d/fedora-updates.repo in a text editor with sudo or admin rights

under [updates]
comment out the metalink with a #symbol at the front of that line.
remove the #symbol from the baseurl entry and alter the address so that it reads as follows for a 64-bit system:

http://download.fedoraproject.org/pub/fedora/linux/updates/26/x86_64

or for 32-bit:

http://download.fedoraproject.org/pub/fedora-secondary/updates/26/i386/
then save the changes and try again

comment out the metalink with a #symbol at the front of that line.
remove the #symbol from the baseurl entry and alter the address so that it reads as follows for a 64-bit system:Just don't do that long term, after it updates correctly a time or two, switch back to the metalink mode

[papai]

Same error again, after /etc/yum.repos.d/fedora-updates.repo file update.

even, ping google.com gives the following:

PING google.com (172.217.31.14) 56(84) bytes of data.

--- google.com ping statistics ---
8 packets transmitted, 0 received, 100% packet loss, time 7185ms



although, the proxy configured properly in terminal !!!

[antikythera]

try disabling IPv6 in your network settings.

[papai]

Oh! god....
Finally its done by exporting the proxy manually !!!!

Thanks a lot for extending your kind supports....
