@stevie pup :-
ATM, I'm using v0.19.2 beta. I only upgraded it once after the last update; TBH, I haven't used it very much recently. I've been watching YT in Opera. So apologies for the lack of newer releases.
Just so's you know for future reference.....the 'portable' is built around the AppImage anyway. If you've been running the portable and it's worked OK till recently, that's what you have been using.
v0.19.2 is working fine here under the elderly Tahrpup 64, but then like most of my 'buntu-based Pups, it's running a much newer kernel and a much-upgraded glibc, amongst other things. (Tahrpup's 3-series kernel doesn't recognise my audio chip; it requires at least 4.1 before it'll behave itself. Not surprising, given that the audio chip didn't even exist at the time of Tahr64's original k3.14.56).
I tried the v0.21.3 build a couple of days ago in my usual daily driver, an even more highly upgraded Xenialpup 64. It pouted.....and segfaulted. Probably wants newer libraries, is my guess. I'm not certain if it wants a newer libcrypto or libssl, stuff like that. It's quite likely.
The included 'lib' directory was put together for me some 6 or 7 years ago, by battleshooter.....an amazing lass whose skills will need no introduction to long-time Puppians. Amazingly, these dependencies still function for the clones and Electron-based apps, though I'm expecting to have to figure out a new batch before long. I believe she managed to find development source code for every item, then compiled the lot from scratch. At the time, these were several releases ahead of what mainstream distros were then using.......which is why, I think, they've lasted so long.
I haven't been in Fossapup 64 for quite a while. I'll have a look tomorrow, see what happens with v0.21.3, like.
Mike.
