Good day!
I have tried XenialPup64 7.5:
And found two annoying bugs, which are very important to fix for me.
First, the Latvian keyboard layout is absent in initial setup screen and in keyboard layout selection screen. Lithuanian and Estonian exist, but Latvian does not exist.
Fortunately, I was able to find Latvian keyboard layout in Advanced keyboard options, but then I found another bug.
Second, keyboard layout variants does not working at all. I have tried several Latvian keyboard layout variants, and none of them is working. No matter, how many times I reboot graphical server, they simply don't work...
Fixing these bugs is very important for me, because I often need to write documents on Latvian language.
