401 Unauthorized error

[muttleytm]

I added to an older, similar thread but not response after several days, so will post a new thread. This issue is also a little different as well.

I have a similar error. On download I get an error: urllib.error.HTTPError: HTTP Error 401: Unauthorized.

My install is a little different. I run Linux Mint 22 and can't install the python dependencies with PIP. PIP is not allowed. I also saw your alternative method using Mamba. The file manager does not recognize Mamba. I have seen some references to using Samba and Conda which I think is part of Anaconda.

I thought of maybe installing it as flatpak and got some instructions on how to do that so that is what I did. used flatpak to install qgis and the dependencies. It prompted me whether I wanted the current stable version of the long term release and I chose LTR. 3.28.9-Firenze was what was installed.

I see you recommend reinstalling the app and plugins, but my install is a little different. I alsh had qgis 3.4x installed before and got nowhere with the PIP issue. I then did uninstall and purge. At one point before I did the Flatpak install I did something and got a message saying that QGIS was already installed although it was nowhere to be found. I did read a discussion that some remnants might be left in a hidden file somewhere. So maybe that is the cause of something.

I copied and pasted the same login and passwords for the NASA/USG site and the Copernicus site that I log it to them. I was also to the search and find images in the time range I specified and viewed them.

I thought I'd post this here in hopes of both getting some good advice and provide some feedback on at least the Linux Mint situation.

I did search to see what versions of Linux allow PIP and didn't find much. I thought maybe make a live USB with that OS on it and QGIS with SCP on it might be another way.

The plugin looks like it does all sorts of great things and is just what I need to do what I want to do. There is a learning curve an I'm at the bottom. So far have spent a lot of time just with figuring out the install.

Hello @muttleytm ,

My install is a little different. I run Linux Mint 22 and can't install the python dependencies with PIP. PIP is not allowed.

PIP is available in several Linux distributions, for instance in Ubuntu https://launchpad.net/ubuntu/+source/python-pip

I thought of maybe installing it as flatpak

At the moment I don't recommend Flatpak.
I suggest to follow these instructions
https://semiautomaticclassificationmanual.readthedocs.io/en/latest/installation_debian.html

It prompted me whether I wanted the current stable version of the long term release and I chose LTR. 3.28.9-Firenze was what was installed.

QGIS 3.28.9-Firenze is quite old, I suggest to install the most recent version.

I copied and pasted the same login and passwords for the NASA/USG site and the Copernicus site that I log it to them. I was also to the search and find images in the time range I specified and viewed them.

Your issue might be caused by a wrong installation, so it should work once the plugin is correctly installed.

Thank you so much for the reply.

I thought I'd go ahead and try the pip3 -env method.

mkdir venv_1

then changed to that directory and activated it

mkdir venv_1
mkdir venv_1

Then I ran to install pip3-env

apt install python3.12-venv

Then I followed the instructions for installing QGIS

sudo apt-get update
sudo apt-get install qgis python3-matplotlib python3-scipy

The insttuctions said to close QGIS, but I never opened it and went directly to:

pip3 install --upgrade remotior-sensus

I got no errors.

I went to Applications menu and didn't see a new version of QGIS. I then ran qgis in the terminal and a different version installed that what I had previously installed

QGIS 3.34.4-Prizren opened and so did this error:

Couldn't load SIP module.
Python support will be disabled.

Traceback (most recent call last):
File "", line 1, in
ModuleNotFoundError: No module named 'qgis'

Python version:
3.12.3 (main, Nov 6 2025, 13:44:16) [GCC 13.3.0]

QGIS version:
3.34.4-Prizren 'Prizren', exported

Python path:
['/usr/share/qgis/python', '/home/tom/.local/share/QGIS/QGIS3/profiles/default/python', '/home/tom/.local/share/QGIS/QGIS3/profiles/default/python/plugins', '/usr/share/qgis/python/plugins', '/usr/lib/python312.zip', '/usr/lib/python3.12', '/usr/lib/python3.12/lib-dynload', '/home/tom/venv_1/.venv/lib/python3.12/site-packages']

Figured I'd stop at this point and post.

You are welcome @muttleytm .
Unfortunately I think it is an issue with the compiled version of QGIS in your distribution. Maybe you can try Ubuntu.
