Symptoms

Uninstallation of PVA Agent fails with error:

[root@vz ~]# pva-setup --uninstall
...
       > Performing PVA 6.0 preuninstall configuration
        > Checking dependencies
[ERROR] Dependency check failed:
        libVZLBackup.so()(64bit) is needed by (installed) vzmigrate-4.0.0-152.x86_64
        libVZLConnection.so()(64bit) is needed by (installed) vzmigrate-4.0.0-152.x86_64

Cause

1) It is not possible to update PVA Agent to version 6.0 if you are using Virtuozzo 4.6, 4.0 or lower. The latest version PVA 6.0 is supported only by Parallels Cloud Server 6.0, Parallels Virtuozzo Containers for Linux 4.7 and Parallels Server Bare Metal 5. For more information you may refer to PVA releases schema.

2) For Virtuozzo 4.0 there are broken dependencies:

[ERROR] Dependency check failed:
        libVZLBackup.so()(64bit) is needed by (installed) vzmigrate-4.0.0-152.x86_64
        libVZLConnection.so()(64bit) is needed by (installed) vzmigrate-4.0.0-152.x86_64

Resolution

In order to resolve the issue with dependencies please perform the following steps:

1) Manually delete vzmigrate package, skipping dependencies:

# rpm -e vzmigrate-4.0.0-152.x86_64 --nodeps

2) Uninstall PVA Agent:

# ./pva-setup --uninstall

3) Install PVA Agent:

# ./pva-setup -r local --install

4) Locate the deleted on step 1 vzmigrate package:

# find /vz/vzup2date/ -iname 'vzmigrate*'

5) Install the found package:

# rpm -ivh /vz/vzup2date/virtuozzo/linux/x86_64/4.0.0/TU-4.0.0-559/vzmigrate-4.0.0-152.x86_64.rpm
