(1) I would like to update PHD2, trying this I just get a "firefox crashed" message. I already tried the Firefox issue fix posted elsewhere in this forum, Terminal based, which failed.
Occasionally Kstar thinks its April, and that bug does nor appear to be startup related. somewhere between focussing and plate solve the date changes, seems to just jump one month forward...
Astroberry? (not stellarmate?)
I got around the (firefix doesn't like the mini linux versions) by installing chrome. Since there no working browser to get chrome, that was a problem. I did some guessing and do a apt-get install chrome or some such - maybe google "adding chrome to linux" for the terminal commands. I'm sure that's how I found it. Once you get Chrome working you can download the latest PHD2.
I instead upgraded to Stellarmate OS (comes with chrome instead) much better network utils and other features like serial port mapping. Plus it helps support the project and Jasems work. I'm assuming astroberry because Smate already comes with chrome installed. (and I think teamviewer) which I also had to install manually with a apt-get install teamviewer.... Also I believe that the PHD on the Smate system was already the latest version.
It's well worth the 49.00. (and a quick download). I've already gotten more than my moneies worth in personal support by having Jasem log into my computer and control my dome and scope from Kuwait. (wow mind boggling). If someone would have said to me back when I bought my first scope that SOMEDAY... I would have my own observatory... what? NO WAY - and someone will be able to use it from the other side of the planet. I'd likely have wet my pants with anticipation. = )
Why don't you update PHD2 with a regular "sudo apt update; sudo apt upgrade"? PHD2 receives updates thorough standard ubuntu system updates so overwriting existing installation with a binary file downloaded from a website is not good idea. It might even break the integrity of update system.
BTW. instead downloading any file with a web browser you can use terminal command "wget URL_TO_FILE". It will download whatever you want without running a browser.
