Problem:
When trying to install a package using rpm-ostree, you see an error message like
error: Transaction in progress: deploy --lock-finalization revision=5040eaabed46962a07b1e918ba5afa1502e1f898bf958673519cd83e986c228f --disallow-downgrade
Solution:
The error message means that currently there’s an rpm-ostree operating in progress and you need to wait for it to finish.
In order to see which process is running, use
ps aux | grep rpm
Example output:
[root@CoreOS uli]# ps aux | grep rpm root 730 41.2 1.7 1218036 34568 ? Ssl 18:41 0:30 /usr/bin/rpm-ostree start-daemon zincati 1896 0.0 0.8 481172 17324 ? Sl 18:41 0:00 rpm-ostree deploy --lock-finalization revision=5040eaabed46962a07b1e918ba5afa1502e1f898bf958673519cd83e986c228f --disallow-downgrade root 3223 0.0 0.0 221452 832 pts/0 S+ 18:42 0:00 grep --color=auto rpm
As you can see in the second line:
zincati 1896 0.0 0.8 481172 17324 ? Sl 18:41 0:00 rpm-ostree deploy --lock-finalization revision=5040eaabed46962a07b1e918ba5afa1502e1f898bf958673519cd83e986c228f --disallow-downgrade
the user zincati is currently running rpm-ostree on my system. zincati is the Fedora CoreOS auto-updater – in other words, an automatic system update is currently running on CoreOS.
In case the process got stuck and waiting doesn’t help reboot the system. Killing the process won’t work.
