Parallels 20.2.0 Linux VM Tools Install Failures

Running latest 20.2.0 (55872) running across most of our team on Ubuntu 22.04 images loaded through Vagrant. Kernel `Linux vm-name 5.15.0-116-generic #126-Ubuntu SMP Mon Jul 1 10:08:40 UTC 2024 aarch64 aarch64 aarch64 GNU/Linux`.
In all cases Parallel Tools says installed but the shares can't be mounted due to prl_fs not being available. During manual install of the tools it complains the DKMS conf is not valid (there is a syntax error in the conf file). The prl_fs_freeze module gets installed but the prl_fs which makes it unable to mount shared folders.

Reinstalling 20.1.3 has no issues.
 
Can confirm.

Start installation of prl_notifier kernel module
/usr/lib/parallels-tools/kmods/dkms.conf: line 34: unexpected EOF while looking for matching `"'
/usr/lib/parallels-tools/kmods/dkms.conf: line 35: syntax error: unexpected end of file
dkms.conf: Error! No 'DEST_MODULE_LOCATION' directive specified.
dkms.conf: Error! No 'PACKAGE_NAME' directive specified.
dkms.conf: Error! No 'PACKAGE_VERSION' directive specified.
Error! Bad conf file.
File: does not represent a valid dkms.conf file.

The error on the line in question is the unmatched double-quote missing at the end of the line:
MAKE="make -f Makefile.kmods KSRC=$kernel_source_dir KVER=$kernelver
This needs repackaged and rereleased by the maintainer to be fixed, as it's gunzipped by the installer and the mounted image is read-only.
I was able to get around it by copying the contents of the mounted /media/cdrom0 to a directory in my home folder, gunzipping the tar.gz, editing the file, removing and recreating the tar.gz back to the kmods subdirectory, and then running the installer from that path as sudo.
 
While building worked, it appears that the shared local folder did not mount, even after reboot. If I tried to add a new share, Parallels crashed.
I tried to `sudo update-initramfs -u -v` and observe the mkinitramfs process but all I saw out of the ordinary was:

Calling hook linux-firmware
find: '/var/tmp/mkinitramfs_bq3FD3/lib/firmware': No such file or directory

Not sure if this is helpful, but worth mentioning.
 
While building worked, it appears that the shared local folder did not mount even after a reboot. I guess we're waiting for the next update.
 
@JamesD48 I don't believe that the parallels tools installer is building the correct prl_fs module and thus the shared folders wont mount. I've also built the tools manually, installed them, and the only kernel module actually installed is the prl_fs_freeze which can't be used as a fs type.

Definitely low on the QA for this release..
 
I am have the same issue when trying to build fresh Ubuntu 22.04 vagrant box using packer. Cannot mount the shared drives due to missing 'prl_fs' filesysytem. Getting the same error with the misconfigured dkms.conf file during tools installation.
