Linux Mint Upgrade tool not working (FileNotFoundError)

[GenesisGreen]

When I try using the Mint Upgrade tool on Linux Mint 20.3, the tool does no go past the "Upgrade to Linux Mint 21 'Vanessa'" screen.
The terminal gives me this:

Code: Select all

The last line gives an error that a file was not found, so I assume I need that file in order to update, however I do not know how to obtain it.

Until now there does not yet an announcement for this tool and following that no instructions. You are too early. What you can do is a timeshift restore.

The same is with me. As soon as I click on "let's go" button this happens:

And, for the record, /usr/share/python-apt/templates/Linuxmint.info file exists.

Maybe the probem lies in double backslah in the address:

/usr/share/python-apt/templates//Linuxmint.info

cheers

And, for the record, /usr/share/python-apt/templates/Linuxmint.info file exists.

Can you double check that? The error is:
FileNotFoundError: [Errno 2] No such file or directory: '/usr/share/python-apt/templates//Linuxmint.info'

That file does not exist here. There is a LinuxMint.info file in that directory but not a Linuxmint.info for me (but I'm on a Mint 21 install). Filenames are case sensitive.

And successive forward slashes in paths are ignored. That's not what the problem is here.

[smudos]

yep, it's

/usr/share/python-apt/templates/LinuxMint.info

with capital M.

Should I try renaming it? There is also /usr/share/python-apt/templates/LinuxMint.mirrors Should that be renamed too?

[xenopeek]

We don't understand why we didn't run into this error in testing, or why other users aren't running in to it, but maybe renaming the file for your situation is needed. BTW do you have Update Manager installed or did you maybe remove that?

But first double-check please. Open a terminal and run the command:
lsb_release -a
For the Distribution ID does that say "Linuxmint" or "LinuxMint"?

If it says "Linuxmint" then yes renaming the file may let you proceed with the upgrade. We're not sure yet but if you're willing to try, we would appreciate that and your feedback! Don't rename the .mirrors file; it is referenced from the .info file and is good. To rename the file run:
sudo mv -v /usr/share/python-apt/templates/LinuxMint.info /usr/share/python-apt/templates/Linuxmint.info

[mtwebster]

Also, can you list the files in that folder with

Code: Select all

ls -la /usr/share/python-apt/templates

Thanks

[smudos]

I changed file name and it all worked as it should -> system successfully upgraded

Before successfull upgrade lsb_release -a gave

Code: Select all

No LSB modules are available.
Distributor ID:	Linuxmint
Description:	Linux Mint 20.3
Release:	20.3
Codename:	una

After upgrade its:

Code: Select all

No LSB modules are available.
Distributor ID:	Linuxmint
Description:	Linux Mint 21
Release:	21
Codename:	vanessa

And now, after upgrade, /usr/share/python-apt/templates lists both files: LinuxMint.info and Linuxmint.info. Is that OK? Should one of be removed or renamed and if so which one?

I have this same exact problem. I'll run the same correction here and see if it solves the problem and then give feedback if it worked or not.

[xenopeek]

Please anybody with the issue, before you make changes also run:
ls -la /usr/share/python-apt/templates

And share the output here. The developer above asked for it, to help with figuring out the cause.

Sorry, saw this too late. But the changes did work for me, so thanks a lot any how
