dosxyz_show Ubuntu does not work

[Mariag-hub]

Hi everyone!
I'm new to the esgnrc world and I have some problems displaying the dose map on my phantom. I successfully did a simulation and I've seen the results using Victoria program online.
When I try to open the same phantom and 3d dose map using the dosexyz_show app it goves me an error

gray shades: 128
128 gray shades allocated!
X Error of failed request: BadName (named color or font does not exist)
Major opcode of failed request: 45 (X_OpenFont)
Serial number of failed request: 744
Current serial number in output stream: 749

Does anyone know how to solve this? I'm using Ubuntu, and I know that this tool only works on Linux distributions, so I thought it would have worked just fine.

Thank you in advance.

It looks like a font package is missing, which version of ubuntu are you using? Try installing the following one at a time, and let me know which one fixes it:

xorg-font-util
xorg-fonts-100dpi
xorg-fonts-75dpi
xorg-fonts-alias
xorg-fonts-encodings
xorg-fonts-misc
xorg-fonts-type1
xorg-mkfontscale

I'm using Ubuntu 22.04.3 LTS. When I try installing one of these packages it gives me the same error:
E: Unable to locate package xorg-fonts-alias
I tried also updating apt-get install but nothing works for now

Sorry that was for Fedora, my mistake. Try these. If they don't work, you may have to search for other font packages.

xfonts-base
xfonts-100dpi
xfonts-75dpi
xfonts-cyrillic

By the way, it's also safe to just use VICTORIA instead, dosxyz_show is not superior.

Thanks, I had to install both xfonts-base and xfonts-cyrillic to make it work. Thanks for your help
