regolith-gdm3-theme could not be installed and also removed

[teeratornk]

Hi,

I am using regolith 1.4.1.

I was trying to change the background of the login screen by installing regolith-gdm3-theme.

Then I have this error

'''
dpkg: error processing archive /var/cache/apt/archives/regolith-gdm3-theme_2.0.0-1ubuntu1ppa1
_amd64.deb (--unpack):

'''

Then I try 'sudo dpkg --configure -a' and 'sudo apt-get install -f.' It does not work and shows the same error.

Now I am trying to remove it.

'''

Do you have any recommendations on how to fix it?

Thank you!

Hi @teeratornk , sorry for the delay, I was on a vacation. If you installed Regolith via ISO (not PPA), then lightdm is the display manager and you will need to use lightdm packages to customize it. If you installed Regolith via PPA and are using gdm3, any other gdm3 package should work.

I'm guessing that since the postinst script failed for you, you are using the lightdm display manager and if so please try out other gtk-based lightdm themes.

I see! Thank you very much for your recommendation! I will try and let you know how things go.
