I am using 18.04. I had Adapta theme as default which I installed a couple of months ago. Now that I tried Ubuntu on a new machine, PPA from Tista does not work at all. There is no way to find an installation method either on their Github page.
I know the author is looking for a new maintainer. Does that mean that we can’t use Adapta anymore ?
If you have any workarounds, do share. Thanks.
I thought I had read something from @abhishek on It’s Foss which might help you, so looked back and found this , https://itsfoss.com/install-themes-ubuntu/ don’t know if it will help but might be worth looking at
this link has an “if the ppa doesn’t work” section.
Thanks @ElectricDandySlider , @01101111
Didn’t work. Looks like it is no longer available.
Luckily, when I tried the PPA in the AskUbuntu link, it worked. :happy:
Can you mark this as solved then with the post that solved it for us - or we moderators might get a bit grumpy 
okay that’ll be just be me. I would help others in our community if they have the same problem to know where the solution was - thanks
Done @ElectricDandySlider
