@dtzWill 1.19.2 just came out I see an update.nix.
Not sure how it's supposed to be run but here are some info:

@dtzWill 1.19.2 just came out I see an update.nix.
Not sure how it's supposed to be run but here are some info:

That's exactly what it does--just informs an update is available and lists new hashes. Requires a bit of manual work to actually change the expression.

Unfortunately I'm not optimistic that this does anything not in the various 1.19.2 beta's--and indeed updating to 1.19.2 doesn't seem to fix things for us.

Folks elsewhere say that we wouldn't experience crashes if we wrapped with 5.10 Qt instead of 5.11,
or perhaps using the bundled libraries. I feel like this has gone back-and-forth a few times, I'm not sure anymore what the "recommended" route is, but perhaps worth trying it to get things working again.

Additionally it looks like we are repackaging the debian package, not the "generic" package--may be worth revisiting that as well.

Update: packaged (quick-and-very-dirty) using buildFHSUserEnv and was able to run mendeley without crashing when using the bundled pdf viewer (annotations/etc).

So there's hope! Let's see if there's a good way to do this w/o user namespaces... :)

@dtzWill would you mind sharing your expression ? I would like to get mendeley working as normal to prepare a presentation and I would be curious to see a buildFHSUserEnv expression at the same time since I never used it.

sorry for delay, this should do the trick: https://github.com/dtzWill/nixpkgs/releases/tag/mendeley-userenv-fix-pdf-viewer-messy

LMK if it helps or doesn't! Good luck!

Oh actually here's a small touchup, but same thing: https://github.com/dtzWill/nixpkgs/tree/experimental/mendeley-userenv-kludgery

This should get you started:

$ nix-env -f https://github.com/dtzWill/nixpkgs/archive/experimental/mendeley-userenv-kludgery.tar.gz -iA mendeley

The .desktop doesn't work I don't think? But should run okay, does for me O:).

it works here thanks. The .desktop seems just fine (maybe after your touchup).

I get

Thanks for the update. On my side I got fed up with Mendeley for not fixing this plus I would rather use open source software so I turned to Zotero. I am not fond of the firefox-based interface and I miss mendeley UI/features but in the long term, it's best to run FOSS software so I will try to stick with it.
Sadly zotero also seems to be built in a FHS env.
Fun fact is that, one month after zotero rolled out the mendeley import feature, mendeley started cyphering its database ("for GPDR" haha...). Hopefully mendeley keeps some backups and I had one not cyphered yet.
