Symptoms
On a Plesk for Linux server on RHEL/AlmaLinux/Rocky Linux/CentOS 8 with MariaDB, Plesk Installer fails:
Unable to retrieve the information about the packages installed in the system:
Failed to read output from the rpm utility.
Error in Package::createFromCache: input line 60894: P:config(mariadb-connector-c) = -1
Version is not specified. Error in Version.cpp.
Or:
Error in Package::createFromCache: input line 32787: P:config(mariadb-connector-c-devel) = -1
Cause
On February 12th, 2022, MariaDB released the following updated versions: 10.3.34, 10.4.24, 10.5.15, 10.6.7.
These updates contain bug MDEV-27834 that results in the incorrect "provides" in the package MariaDB-shared (and MariaDB-devel) that breaks Plesk Installer.
Resolution
Apply one of the following workarounds:
Downgrade the package
-
Connect to the server using SSH.
-
Downgrade the package
MariaDB-shared:# yum downgrade MariaDB-shared
Note: in case of the error message being
mariadb-connector-c-devel, it's required also to downgradeMariaDB-devel -
Exclude the affected package to avoid it from being installed:
Note: The name of the repository file
/etc/yum.repos.d/MariaDB.repois just an example, it can have a different name.-
for MariaDB 10.3:
# echo "exclude=MariaDB-shared-10.3.34-* MariaDB-devel-10.3.34-*" >> /etc/yum.repos.d/MariaDB.repo
-
for MariaDB 10.4:
# echo "exclude=MariaDB-shared-10.4.24-* MariaDB-devel-10.4.24-*" >> /etc/yum.repos.d/MariaDB.repo
-
for MariaDB 10.5:
# echo "exclude=MariaDB-shared-10.5.15-* MariaDB-devel-10.5.15-*" >> /etc/yum.repos.d/MariaDB.repo
-
for MariaDB 10.6:
# echo "exclude=MariaDB-shared-10.6.7-* MariaDB-devel-10.6.7-*" >> /etc/yum.repos.d/MariaDB.repo
-
Update the RPM database only
-
Connect to the server using SSH.
-
Download and downgrade the package manually with keeping new libraries:
-
