Re: [darktable-user] Time for a new system
To piggyback on Chris' comments, there's a relatively new remote personal cloud storage option known as the AmberPRO - https://shop.myamberlife.com/collections/all/products/amber?variant=22314078404666. Put one of these at a friend's home in another part of the region. Set it up on its own UPS, with Ethernet surge protection such as this - https://www.amazon.com/Ubiquiti-ETH-SP-G2-Surge-Suppressor-Protector/dp/B079HXKRW1/ref=asc_df_B079HXKRW1?tag=bngsmtphsnus-20=df0=79989588513695=s=e=be=c===pla-4583589115360178=1 to guard against lightning surges. You can even plug in an external hard drive (or SSD) for additional storage. Hard to beat this option.

Re: [darktable-user] Corrupted installation of darktable on Linux Mint 21
In checking today, the System Monitor (as suggested) showed only the error message window as shown below. There were no darktable-related processes running (which I anticipated, given that darktable refused to start). I ran the ps tool that Remco suggested, and got the same results. I could find NO lock files related to darktable anywhere on the system; neither data.db.lock nor library.db.lock (p. 287 in The Fine Manual). What to do now? I moved data.db and library.db to the desktop. Lo and behold, darktable started normally. I have to presume that one or the other were corrupted, so both got deleted. In any case, darktable is once again up and running. I am looking forward to v4.2.0 popping out of the chute in the very near future. Thanks to Butch and Remco for their suggestions.

I am NOT a Linux wizard and haven't a good idea of how to resolve this issue. Anyone got some good advice? I'm hoping to come to a successful resolution before darktable 4.2 springs out later this month.

You need to open that and make sure you are on the Processes tab. If you see one called 'darktable', press End Process on the lower right border of the System Monitor window, then press End Process on the pop-up. Check to make sure you do not have multiple darktable processes.
