Qpress: command not found when running decompress (same xtrabackup version works on an older OS)

MySQL & MariaDB Percona XtraBackup
1

We are trying moving our servers to oracle linux 8 from centos 7.
on the old centos 7 the xtrabackup is:
xtrabackup version 8.0.14 based on MySQL server 8.0.21 Linux (x86_64) (revision id: 113f3d7)

On the newer server with oracle linux 8 its the same version:
xtrabackup version 8.0.14 based on MySQL server 8.0.21 Linux (x86_64) (revision id: 113f3d7)

On the old server decompress works but on the newer server I get
qpress: command not found when running decompress

RPMs installed on old server:
percona-xtrabackup-test-80-8.0.14-1.el7.x86_64
percona-xtrabackup-80-debuginfo-8.0.14-1.el7.x86_64
percona-xtrabackup-80-8.0.14-1.el7.x86_64

RPMs installed on new server:
percona-xtrabackup-80-8.0.14-1.el8.x86_64
percona-xtrabackup-test-80-8.0.14-1.el8.x86_64
percona-xtrabackup-80-debuginfo-8.0.14-1.el8.x86_64

Which qpress on old server:
which qpress
/bin/qpress

which qpress on new server:
which qpress
/usr/bin/which: no qpress in (/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/var/lib/mysql/.local/bin:/var/lib/mysql/bin)

Why is qpress not in the new rpm?
Can I install qpress seperately?
Also when I run an xtrabackup compress on the new server it compresses correctly ( i am able to decompress the backups using the old server and am able to restore the backup to the new server)
Not sure why it cant find qpress in the new server.

Thanks

After manually installing qpress from the Oracle linux repo the error is gone.

Not sure why we did not need to manually install qpress before. Does the xtrabackup rpms try and download the qpress from the percona repo seperately? that might be the issue.

Hello @ipcmlr,
Not sure. I’ve always installed qpress as a separate package. It won’t be needed anymore once you move to modern xtrabackup as it uses zstd natively.

Make sure your PXB and MySQL versions match exactly.
