YUM Downgrade Package Which Have Dependencies

YUM downgrade is more difficult with packages that have dependencies. YUM downgrade does not resolve dependencies automatically, so it must be done manually.

YUM Downgrade Package and Dependencies

yum downgrade lib1 lib2 package
Example: check package dependencies manually
yum downgrade sqlite

Setting up Downgrade Process
Resolving Dependencies
--> Running transaction check
---> Package sqlite.i686 0:3.6.22-1.fc13 set to be downgraded
---> Package sqlite.i686 0:3.6.23-1.fc14 set to be erased
--> Finished Dependency Resolution
Error: Package: sqlite-devel-3.6.23-1.fc14.i686 (@rawhide/12)
           Requires: sqlite = 3.6.23-1.fc14
           Removing: sqlite-3.6.23-1.fc14.i686 (@rawhide/12)
               sqlite = 3.6.23-1.fc14
           Downgraded By: sqlite-3.6.22-1.fc13.i686 (fedora)
               sqlite = 3.6.22-1.fc13
 You could try using --skip-broken to work around the problem
SQLite package depends on sqlite-devel package, so both (sqlite-devel and sqlite) have to be downgraded:
yum downgrade sqlite-devel sqlite
