CentOS 7 Is Broken for Upgrade
In the last few year RedHat destroyed CentOS 7. Now we’ve moved on to Debian, Ubuntu, and Alma Linux.
If you have an old system, you’ll see a number of errors. The big clues are `yum update` fails and `yum upgrade` fails.
Step 1 – Fix the 404s.
Typically they start off with a 404. It’s a long hairy message about the repository configuration, but the top will look like this:
... http://mirror.centos.org/centos/7/sclo/x86_64/rh/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found
or this:
... Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=genclo error was 14: curl#6 - "Could not resolve host: mirrorlist.centos.org"
They end list this:
Cannot find a valid baseurl for repo: base/7/x86_64
Replace the mirror lists:
sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-* sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*
Next yum upgrade again.
Step 2 – Fix invalid baseurl centos-sclo-sclo repo
You’ll see a big message again and at the bottom:
Cannot find a valid baseurl for repo: centos-sclo-sclo
Remove the broken repo:
mv /etc/yum.repos.d/CentOS-SCLo-scl.repo /etc/yum.repos.d/CentOS-SCLo-scl.disabled
Virtualmin unauthorized
failure: repodata/repomd.xml from virtualmin: [Errno 256] No more mirrors to try. https://5600280:gKIdVAzi2J@software.virtualmin.com/vm/6/centos/7/x86_64/repodata/repomd.xml: [Errno 14] HTTPS Error 401 - Unauthorized
You need to update your license or do this on a legacy system:
virtualmin downgrade-license --perform
Virtualmin package no signed fix
Package wbm-virtual-server-7.20.1.gpl-1.noarch.rpm is not signed
Upgrade so:
yum upgrade --nogpgcheck
You will cry at Stack
sqlite problems
Disable that bad repo
yum-config-manager --disable centos-sclo-rh yum-config-manager --disable centos-sclo-sclo
Maybe try this if it fails again:
yum remove sclo-php55-php-pecl-imagick

virtualmin setup-repos did not change the contents of /etc/yum.repos.d/virtualmin.repo on my CentOS 7 (although the timestamp of the file changed) so I tried a manual update:
wget https://software.virtualmin.com/vm/7/rpm/virtualmin-gpl-release.noarch.rpm
rpm -Uvh virtualmin-gpl-release.noarch.rpm
warning: virtualmin-gpl-release.noarch.rpm: Header V4 RSA/SHA256 Signature, key ID b9a0b8b7: NOKEY
