I have used Inkscape daily for years, and since the auto update to version 1.2, none of my previous .svg files will open. In the opening sequence, none of the suggested existing files will open, and opening from the file itself will not work.

Now, and before the update, clicking 'Save As' closes the window, so I cannot create any new files. I have been re-using old files and have put a lot of work into them, so do not wany to lose them.

Also, previously and now, numerical entry is scrambled. If say, I want to re-size something and type a number, it will only accept one numeral at a time. So, if I type 123, it comes out as 231.000. I can get around that by typing 1, enter, then adding the 2, enter, ... but it is a pain.

Is it just a Ubuntu thing? Might it be different if I upgrade Ubuntu? Should I delete Inkscape and try a fresh download? Thank you <3

Enclosed example of my work.

Before we go further, please click the Reset Preferences button in the Preferences>System, then restart Inkscape.

Thank you Tyler, nothing seemed to happen when I pressed Reset Preferences, no difference in behaviour. Tried several times and rebooted laptop too.

Ok... We probably need a sample svg file to go further.

Thank you Tyler <3 Can I just drag and drop a file here, guess I will find out. I am pretty sure it is a conflict with Ubuntu, I may have to take the plunge and upgrade to Ubuntu Studio. All the files opened fine before Inkscape upgraded, so it is something to do with the upgraded version, not the file. I would be quite happy if I could revert to the older version. Not sure if that worked?

I think that is only the file image, the svg file would not load?

The thumbnail is the svg file. It's fine.

The file opens in 1.2 here, Mint 20.3.

I'd uninstall Inkscape and reinstall. 

I have a very similar issue to this on Ubuntu (Gnome).

Inkscape is essentially completely broken:

The save/save as options under file do nothing, and I cannot import any images at all into Inkscape.

Was working perfectly fine before so I assume some recent update broke it for Ubuntu.

A quick patchwork solution is to use this minimum SVG code in a text file, rename it asz you liem then open

Germen, I am sorry, I do not follow what you are suggesting there?

Tyler Durden, I followed one instruction for romoving inkscape that began with cd /etc/apt/sources.list.d/, but is said file not found.

Was going to try another method,but not sure which level of removal I need?

Uninstall inkscape

To uninstall just inkscape package itself from Ubuntu execute on terminal:

sudo apt-get remove inkscape

Uninstall inkscape and it's dependent packages

To uninstall the inkscape package and any other dependant package which are no longer needed on Ubuntu.

sudo apt-get autoremove inkscape

Purging inkscape

If you also want to delete configuration and/or data files of inkscape from Ubuntu then this will work:

sudo apt-get purge inkscape

To delete configuration and/or data files of inkscape and it's dependencies from Ubuntu then execute:

sudo apt-get autoremove --purge inkscape

I'd just use the first, least draconian method. (I use a package manager, personally).

Hi! 

I've same problem. Inkscape does not work anymore.

If I install previous version via apt-get install inkscape, it installs 0.9 version which does not support all command line options I need, but it opens the SVGs

when I use system package (snap I believe) it installs 1.2-56b05e47e7-2022-06-09-custom but then I cannot open any SVG file anymore. It was working before 
The output is (BTW, I cannot specify input file as it always takes the file from home instead of current directory) 

~> inkscape icon.svg
Gtk-Message: 12:46:56.749: Failed to load module "canberra-gtk-module"
Gtk-Message: 12:46:56.752: Failed to load module "canberra-gtk-module"
ink_file_open: '/home/pablo/icon.svg' cannot be opened!
InkscapeApplication::document_open: Failed to open: /home/pablo/icon.svg
ConcreteInkscapeApplication::on_open: failed to create document!

This issue is still not fixed. I also see the error:

Gtk-Message: 11:25:43.553: Failed to load module "canberra-gtk-module"
Gtk-Message: 11:25:43.555: Failed to load module "canberra-gtk-module"

When launching inkscape. Considering this is broken on the official ubuntu software center, it blows my mind that it's going unfixed.

File opens correctly on UM22.04 Inkscape 1.2, maybe try downloading the Appimage from Inkscape site?
