Yesterday I moved my Plex installation from a Windows machine to a Linux machine. The primary data folders that needed to be copied over were Media, Metadata, Plug-ins, and Plug-in Support. It doesn't hurt to copy over some of the folders in Cache too. It's possible there may be some more data that needs to be moved over, but I don't have documented what.
After moving all the data, I updated the paths in the database for the new machine. Doing this allowed me to keep everything as it was and no new refreshes/scans needed to be done.
The location of the Plex modified SQLite for me was at /usr/lib/plexmediaserver/Plex SQLite. So the following is the bash commands to stop the plex server and open SQLite editor on Linux Mint 21.3.
service plexmediaserver stop
/usr/lib/plexmediaserver/Plex\ SQLite '/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-in Support/Databases/com.plexapp.plugins.library.db'
And the following is the SQL I used to replace a D: drive with a path of /home/plex/drives/d/. You can replace these strings in the below code with your custom drives and paths.
#Replace backslashes with forward slash in paths
UPDATE media_parts SET file=REPLACE(file, '\', '/');
UPDATE section_locations SET root_path=REPLACE(root_path, '\', '/');
UPDATE media_streams SET url=REPLACE(url, '\', '/') WHERE url LIKE 'file://%';
#Replace root paths
UPDATE media_parts SET file=REPLACE(file, 'D:/', '/home/plex/drives/d/');
UPDATE section_locations SET root_path=REPLACE(root_path, 'D:/', '/home/plex/drives/d/');
UPDATE media_streams SET url=REPLACE(url, 'file://D:/', 'file:///home/plex/drives/d/') WHERE url LIKE 'file://%';
UPDATE media_streams SET url=REPLACE(url, 'file:///D:/', 'file:///home/plex/drives/d/') WHERE url LIKE 'file://%';
UPDATE metadata_items SET guid=REPLACE(guid, 'file:///D:/', 'file:///home/plex/drives/d/');

I created this script because I wasn’t happy with the native Roboform importer inside Bitwarden. This fixed multiple problems including:
* Ignoring MatchUrls
* Parent folders weren’t created if they had no items in them (e.x. if I had identities in Financial/Banks, but nothing in /Financial, then it wouldn’t be created /Financial)
* Completely ignoring the extra fields (RfFieldsV2)
This fixes all those problems.
This needs to be ran via php in a command line interface, so `php convert.php`. It requires the [bitwarden cli “bw” command](https://bitwarden.com/help/cli/).
There are 2 optional arguments you can pass:
1) The name of the import file. If not given, `./RfExport.csv` will be used
2) The “bw” session token. If not given as a parameter, it can be set directly inside this file on line #4. You get this token by running `bw unlock` (after logging in with `bw login`).
This script does the following:
* Reads from a csv file exported by Roboform to import into bitwarden
* Runs `bw sync` before processing
* Imported Fields:
* Name: Becomes the name of the item
* Url: Becomes the URL for the item
* MatchUrl: If this is not the same “Url” then it is added as another URL for the item
* Login: Becomes the login (user) name
* Pwd: Becomes the password
* Note: Becomes the note
* Folder: Item is put in this folder
* RfFieldsV2 (multiple):
* Fields that match the login or password fields are marked as “linked fields” to those. If the field names are the following, they are not added as linked fields: *user, username, login, email, userid, user id, user id$, user_email, login_email, user_login, password, passwd, password$, pass, user_password, login_password, pwd, loginpassword*
* Fields that are different than the login or password are added as appropriate “Custom fields”. Supported types: '', rad, sel, txt, pwd, rck, chk, are
* Each field has 5 values within it, and 3 of those seem to be different types of names. So as long as they are not duplicates of each other, each name is stored as a seperate field.
* If all fields are blank but “name” and “note” then the item is considered a “Secure Note”
* While reading the csv file for import, errors and warnings are sent to stdout
* After the csv import has complete, it will give a total number of warnings/errors and ask the user if they want to continue
* Creates missing folders (including parents that have no items in them)
* During export to bitwarden:
* This process can be quite slow since each instance of running “bw” has to do a lot of work
* Keeps an active count of items processed and the total number of items
* If duplicates are found (same item name and folder) then the user is prompted for what they want to do. Which is either s=skip or o=overwrite. A capitol of those letters can be given to perform the same action on all subsequent duplicates.
* Errors are sent to stdout

| Since I have been moving my primary workstation to Linux, I have been in need of finding a new password manager after Roboform failed me. I decided to try out KeePassXC but was having trouble since my Ungoogled Chromium browser was sandboxed in Flatpak. The instructions for this on Unix Stack Exchange were no longer working so I had to dig into it myself.
The 2 primary problems were that:
1) The browsers’ sandboxes did not have the QT libs.
2) The interprocess communication pipe socket had been renamed from kpxc_server to org.keepassxc.KeePassXC.BrowserServer.
The following are the instructions to get KeePassXC running in Flatpak versions of both Chrome and Firefox. This was tested on Linux Mint 21.3 with both Ungoogled Chromium and Firefox. You will need to change the KP_FLATPAK_PACKAGE if you use other versions of Chrome.
-
Run the relevant below environment variables in your command shell before running the commands in the following steps:
#Shared environment variables:
KP_CUSTOM=/home/$USER/keepass-browser
KP_JSON_NAME=org.keepassxc.keepassxc_browser.json
#Chrome environment variables:
KP_FLATPAK_PACKAGE=io.github.ungoogled_software.ungoogled_chromium
KP_JSON_START=~/.config/chromium/NativeMessagingHosts
KP_JSON_END=~/.var/app/$KP_FLATPAK_PACKAGE/config/chromium/NativeMessagingHosts
#Firefox environment variables:
KP_FLATPAK_PACKAGE=org.mozilla.firefox
KP_JSON_START=~/.mozilla/native-messaging-hosts
KP_JSON_END=~/.var/app/$KP_FLATPAK_PACKAGE/.mozilla/native-messaging-hosts
-
Install and enable the browser extension:
KeePassXD > Tools > Settings > Browser Integration:
- Check “Enable Browser Integration”
- Check “Chromium” and/or “Firefox”
- Download the plugin listed on this screen in your browser
- Click "OK"
Note: This creates $KP_JSON_START/$KP_JSON_NAME
-
Set up the needed files in the sandbox:
#Put KeePass proxy and needed library files in user directory
mkdir -p $KP_CUSTOM/lib
mkdir -p $KP_JSON_END #Needed for firefox
cp /usr/bin/keepassxc-proxy $KP_CUSTOM/
rsync -a /usr/lib/x86_64-linux-gnu/libicudata* /usr/lib/x86_64-linux-gnu/libicuuc* /usr/lib/x86_64-linux-gnu/libicui* /usr/lib/x86_64-linux-gnu/libdouble* /usr/lib/x86_64-linux-gnu/libsodium* /usr/lib/x86_64-linux-gnu/libQt5* $KP_CUSTOM/lib
#Copy the JSON file to the Flatpak app directory and change the executable path in the file
cp $KP_JSON_START/$KP_JSON_NAME $KP_JSON_END/
sed -i "s/\/usr\/bin\//"$(echo $KP_CUSTOM | sed 's_/_\\/_g')"\//" $KP_JSON_END/$KP_JSON_NAME
-
Add permissions to the Flatpak:
flatpak override --user --filesystem=$KP_CUSTOM:ro $KP_FLATPAK_PACKAGE #Only required if home directory is not shared to the Flatpak
flatpak override --user --filesystem=xdg-run/org.keepassxc.KeePassXC.BrowserServer:ro $KP_FLATPAK_PACKAGE
flatpak override --user --env=LD_LIBRARY_PATH=$(flatpak info --show-permissions $KP_FLATPAK_PACKAGE | grep -oP '(?<=LD_LIBRARY_PATH=).*')";$KP_CUSTOM/lib" $KP_FLATPAK_PACKAGE

Part 0: Installation
I’ve been moving from Windows to Linux recently and my latest software move attempt is Roboform, a password manager that I use in offline mode. Just running it under Wine works fine for the primary software interaction, but I was unable to get it fully integrated with its chrome extension. Below is the information for my attempt to get it working, in case someone could use the information or wanted to try continuing my attempts.
To move your RoboForm profile to Linux, copy the data from C:\Users\USERNAME\AppData\Local\RoboForm\Profiles\Default Profile to ~/.wine/drive_c/users/USERNAME/Local Settings/Application Data/RoboForm/Profiles/Default Profile.
Part 1: Redirect the extension to the executable
The chrome extension talks to its parent, rf-chrome-nm-host.exe, through the native messaging API. To direct the extension to talk to the windows executable you have to edit ~/.config/chromium/NativeMessagingHosts/com.siber.roboform.json and change the path inside it to /home/USERNAME/chrome-robo.sh, a script file that you will create. You can’t link directly to the rf-chrome-nm-host.exe because it has to be run through Wine, and the path cannot contain arguments.
Create a file with executable permissions at ~/chrome-robo.sh and set its contents to:
cd "/home/USERNAME/.wine/drive_c/Program Files (x86)/Siber Systems/AI RoboForm/9.6.1.1/";
/usr/bin/wine ./rf-chrome-nm-host.exe chrome-extension://pnlccmojcmeohlpggmfnbbiapkmbliob/ --parent-window=0
Part 2: Debugging why it isn’t working
It should have worked at this point, but it still wasn’t, so I had to go further into debug mode. The full copy of the C source code can be found at the bottom of this post. Make sure to replace USERNAME in the source (and instructions in this post) with your username, as using “~” to specify your home directory often doesn’t work in this setup. You may also need to replace version numbers (9.6.1.1 for this post).
First, I created a simple C program to sit in between the chrome extension and the rf-chrome-nm-host.exe. All it did was forward the stdin/stdout between both programs (left=chromium, right=rf-chrome-nm-host.exe) and output their crosstalk to a log file (./log) that I monitored with tail -f. I pointed to the generated executable in the ~/chrome-robo.sh file.
All that was generated on the Linux config was: left=ping, right=confirm ping, left=get product info, END.
I then modified the program to specifically handle chrome native messaging packets, which are always a 4 byte number specifying the packet length, followed by the packet data (IsChrome=1). If this variable is turned off there is a place in the code where you can set a different executable with parameters to run.
Next, I ran the program in Windows with a working left+right config so I could see what packets were expected.
I then added a hack to the program (AddRoboformAnswerHacks=1) to respond to the 2nd-4th packets sent from the left (get-product-info, get-product-info, Initialize2) with what was expected from the right. rf-chrome-nm-host.exe crashed on the 5th packet, and debugging further from there would have taken too more time than I was willing to put in, so at that point I gave up.
Part 3: Trying with windows
I next decided to see if I could get the chromium extension to play nicely by talking directly to the rf-chrome-nm-host.exe on my Windows machine via an SSH tunnel. To do this, I changed the char *cmd[]= line to:
char *cmd[]={
"/usr/bin/ssh",
"USERNAME@HOSTNAME",
"cd c:/Program\\ Files\\ \\(x86\\)/Siber\\ Systems/AI\\ RoboForm/9.6.1.1; ./rf-chrome-nm-host.exe chrome-extension://pnlccmojcmeohlpggmfnbbiapkmbliob/ --parent-window=0",
NULL
};
While the first 4 packets succeeded in this setup, the following packets (rf-api-request) were all met with: pipe open error: The system cannot find the file specified. (error 2).
This was another stopping point because debugging this would also have taken too long. Though I did do some initial testing using Process Monitor and handle lookups in Process Explorer.
Part 4: The C source code
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <sys/wait.h>
#include <string.h>
FILE *SideLog; //This logs all events to the file "log"
FILE *RecordLeft; //This logs the exact packets that the left side sends to the file "left"
int IsChrome=1; //True for roboform chrome compatibility, false to just pass through data as is
int DisplayStatus=1; //Whether to show the "Status: x" updates
int AddRoboformAnswerHacks=0; //Whether to force send fake responses that the rf-chrome server is not responding to
const char* HomePath="/home/USERNAME/.wine/drive_c/Program Files (x86)/Siber Systems/AI RoboForm/9.6.1.1/"; //This must be set.
const char* ExePath="/home/USERNAME/.wine/drive_c/Program Files (x86)/Siber Systems/AI RoboForm/9.6.1.1/rf-chrome-nm-host.exe"; //This must be set. You can make sure rf-chrome-nm-host.exe is running with a 'ps'
//Send back a custom packet to the left. This will show in the log file BEFORE the packet it is responding to.
void SendLeft(char *str)
{
char Buffer[255];
int StrSize=strlen(str);
*(int*)Buffer=StrSize;
strcpy(Buffer+4, str);
write(STDOUT_FILENO, Buffer, StrSize+4);
fprintf(SideLog, "OVERRIDE REQUEST: %s\n\n", Buffer+4);
fflush(SideLog);
