What were you trying to do that didn't work?
When jbcs-httpd24-brotli-xxx.el7jbcs package (delivered by jb-coreservices-1-for-rhel-7-server-rpms repository) is installed on the system, leapp breaks during reboot phase while upgrading with the following error:

The root cause for this is brotli package doesn't get installed on the system, because jbcs-httpd24-brotli-xxx.el7jbcs package claims to deliver libbrotli*.so libraries, which is true, but not system libraries, SCL libraries instead:
# rpm -q --provides -p ./jbcs-httpd24-brotli-1.0.9-2.el7jbcs.x86_64.rpm
[...]
libbrotlicommon.so.1()(64bit)
libbrotlidec.so.1()(64bit)
libbrotlienc.so.1()(64bit)
scl-package(jbcs-httpd24)
# rpm -qlp ./jbcs-httpd24-brotli-1.0.9-2.el7jbcs.x86_64.rpm
[...]
/opt/rh/jbcs-httpd24/root/usr/lib64/libbrotlicommon.so.1
/opt/rh/jbcs-httpd24/root/usr/lib64/libbrotlicommon.so.1.0.9
/opt/rh/jbcs-httpd24/root/usr/lib64/libbrotlidec.so.1
/opt/rh/jbcs-httpd24/root/usr/lib64/libbrotlidec.so.1.0.9
/opt/rh/jbcs-httpd24/root/usr/lib64/libbrotlienc.so.1
/opt/rh/jbcs-httpd24/root/usr/lib64/libbrotlienc.so.1.0.9
Due to this, brotli package, which is implicitly required by dnf, is not part of the transaction, letting dnf and the whole system in an unrecoverable state.
brotli being implicitly required by dnf:
(rhel8) # yum remove brotli
[...]
Error:
Problem: The operation would result in removing the following protected packages: dnf
We can detect the issue prior to rebooting through checking the leapp upgrade log:
- When upgrade will be ok
# grep dnf_dry_run /var/log/leapp/leapp-upgrade.log | grep brotli 2024-01-23 16:30:37.135 DEBUG PID: 13317 leapp.workflow.InterimPreparation.dnf_dry_run: brotli x86_64 1.0.6-3.el8 os8 323 k #
- When upgrade will fail, there is no brotli package in the transaction
# grep dnf_dry_run /var/log/leapp/leapp-upgrade.log | grep brotli #
The workaround consists in making sure brotli is always part of the transaction:
# echo brotli >> /etc/leapp/transaction/to_install
It would hence nice to harden leapp to avoid post-reboot failure, which leads the system in an unrecoverable state.
See also jbcs-httpd24-brotli claims to deliver "libbrotlienc.so.1()", which breaks Leapp upgrades from 7 to 8.
Please provide the package NVR for which bug is seen:
leapp-upgrade-el7toel8-0.19.0-1.el7_9.noarch
jbcs-httpd24-brotli-xxx.el7jbcs (e.g. jbcs-httpd24-brotli-1.0.6-21.jbcs.el7.x86_64)
How reproducible:
Always
Steps to reproduce
- Install jbcs-httpd24-brotli from jb-coreservices-1-for-rhel-7-server-rpms repository
- Upgrade
Expected results
No error or error detected before reboot
Actual results
Upgrade happens but leaves system unrecoverable
