Set path for Profiles to the location on main drive used by W10

Can you explain this in more detail? What exactly did you do?

Thought it was fairly well explained above...standard install for both operation systems; path set to same Profile folded; and what happens when I re-boot and how I currently need to correct the problem with each re-boot. Please let me know what other info you'd like and I'll happily provide same.

The apparent problem as I see it is that once I enter/re-enter the path to the profile folder (in Ubuntu) on the main drive, TB (ProfileManager) fails to save it and the next re-boot of system can not find the path or profile folder until I reenter the path thru ProfileManager.

Can you post the contents of your Ubuntu profiles.ini file?

What is the exact path to the profile folder on the Windows partition?

The Profiles.ini file is:

[General] StartWithLastProfile=1

[Profile0] Name=Default User IsRelative=0 Path=/media/robert/MAIN Drive/Users/Robert A. Cressman/AppData/Roaming/Thunderbird/Profiles/jls91gxq.default

The path to the Profiles folder on Windows is:

C:/Users/Robert A. Cressman/AppData/Roaming/Thunderbird/Profiles/jls91gxq.default

Thanks!

There are spaces in your path, which may cause problems. You need to escape the spaces in profiles.ini with a backslash: Path=/media/robert/MAIN\ Drive/Users/Robert\ A.\ Cressman/AppData/Roaming/Thunderbird/Profiles/jls91gxq.default

Ok, tried that and didn't work. I get the error that the Profile is not accessible, or missing when I boot up. However, it I click on the Thunderbird icon after that, it does boot.

Don't know if this is related, and only as an FYI, but after I made the change, Firefox shows a picture from my hard drive as background to the home and subsequest webpages and I can not make it go away!

Can you post the contents of the adjusted profiles.ini again?

However, it I click on the Thunderbird icon after that, it does boot.

Did it create a new profile at the default location? What profile is being used when you start Thunderbird? You can check via Troubleshooting Information.

That isn't related to Thunderbird. You may ask in the Firefox support group. Just in case if this is related to malware see https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware

I checked the Troubleshooter. If I do not check (tic) "Include Account Names" box, the Profile Directory line shows a radio button stating... "OPEN DIRECTORY" (unknown location).

When I check the box, it changes the Profile directory line to... /media/robert/MAIN Drive/Users/Robert A. Cressman/AppData/Roaming/Thunderbird/Profiles/jls91gxq.default (Unknown location).

This is what the current Profile.ini file reads... [General] StartWithLastProfile=1

[Profile0] Name=default IsRelative=1 Path=Profiles/jls91gxq.default Default=1

[Profile1] Name=Default User IsRelative=0 Path=/media/robert/MAIN\ Drive/Users/Robert\ A.\ Cressman/AppData/Roaming/Thunderbird/Profiles/jls91gxq.default

You do have two profile entries in your profiles.ini now, and they appear to have the same name. That can't be right.

When I check the box, it changes the Profile directory line to...

I don't think checking that box would have any impact on the profile path.

(Unknown location)

Something seems to be wrong with your profile path.

When you use the path as specified in profiles.ini and do a 'cd <path_to_your_profile>' in a terminal, does it work?

Ok, I tried the "cd <path to your Profile>" in terminal and it did not work -No such file or directory. I also copied the Profile folder and Profile.ini file to a different drive (with no spaces) and put them in a new folder. I reset the Profile Manager to the new path and deleted all the other locations in Profile.ini except the new one. ZIP! NADA! Didn't work there either!

I have no idea why not.

In the terminal, start with 'cd /media'. The 'cd' to the next level until you get stuck.

I did as stated. I could not get to the completed path. So, I moved the Profile and Profile.ini to a completely different drive on a path without spaces. I tried the cd / to check the path. I did it in increments starting with /media/. and it went all the way to my profile. I rewrote the path in -profilemanager and exited. I then re-booted completely. I get the same error...

I have no idea why, but Profilemanager does not seem to save/remember the path. When I re-enter the exact same path, it goes there till the next boot.

You cannot move profiles.ini to a different location. Thunderbird does only look for profiles.ini in your home directory: $HOME/<your user id>/.thunderbird/profiles.ini You can move the profile folder referenced in profiles.ini though, what you did.

I had copied the two (Profiles Folder & profiles.ini) to the new drive, so the original was still in the ./thunderbird folder. All back to square one.

I set up thunderbird in windows 10 and migrated my Profiles folder which is on drive E: (via profiles.ini). I then copied the prefs.js file to Linux (Ubuntu 14.04) ./thunderbird/<my Profiles folder>/perfs.js.

I made the path corrections in the Linux perfs.js to point to the Profiles folder on E;. I then opened -profilesmanager and set the new Profiles folder location.

After saving it, I started Thunderbird. All ok. After re-boot, back to not finding the profile.

Problem solved. It had to do with the correct path, but I'm not sure in which file as I made so many corrections and changes, over and over!

Congratulations. Can you then mark the thread as 'Solved' please? Thank you.
