Hi Guys,
You may get the following error when you run the Plesk autoinstaller.
error: cannot open Packages index using db5 - (-30973)
error: cannot open Packages database in /var/lib/rpm
YumBaseError: Error: rpmdb open failed
You are getting this error because some of the RPM packages are corrupted.
Remove the corrupted RPM.
rm -f /var/lib/rpm/__db.*
Now rebuild it.
rpm --rebuilddb
That will fox all the issues.
