Is there a Portableapps for Linux

Update: The best solution I've found for this is appimage.org. They have produced an app, appimagetool, which will compress into a single file the contents of a directory structure - much like the portableapps folder structure. The tool includes a process to redirect configuration references/changes (in lieu of the registry in Windows) to a folder named [program-name].home.

I need to transition my notebook from WIN10 to Linux in 17 months and a big hole in functionality is I cannot find portableapps for Linux. Specifically, I use multiple portable installations of Chrome so I can segregate browser usage to specific browser installations.

I have no idea why MS wants to alienate customers. MS won’t allow an upgrade to WIN11 on my notebook which will run WIN10 as a host OS along with a WIN10 VM and a WIN11 VM concurrently. The only reason given is the processor. From my research it is not an 8th generation processor. I purchased the notebook at a MS store and 5 years later MS says I’m not allowed to install WIN11. Time to go down to the MS store and spend another $1K. Maybe not.

Thanks!!!
