iotop and ncurses compatible versions?

[techie2000]

I previously used iotop without issue.
I came to use it the other day and got errors.
On taking a closer look today I have managed to avoid the errors by manually installing an older version of ncurses.

Errors observed running nerdpack version iotop-0.6-x86_64-1_fs.tgz and ncurses-terminfo-6.1.20191130-x86_64-1.txz :

Installing versionhttps://slackware.uk/slackware/slackware64-14.2/slackware64/l/ncurses-5.9-x86_64-4.txz returns iotop to operational status.

Looking at https://github.com/Tomas-M/iotop it would appear that the version of iotop in nerdpack (0.6) is massively out of date, with v1.20 being releases very recently - and includes pretty graphs of each process.

Could we get this version added?

Hello @techie2000 , what commands did you issue to install the slackware ncurses version on undraid?
I am experiencing this issue as well, and I also echo your comments about the software being out of date.
Thank you all,

Having the same issue. iotop worked previously, however when I tried to use it today I received the error above.

Same issue here, too.

@boomam has provided a solution to keep running the nerd version (0.6) of iotop (#59 (comment)).
For now, I'm keeping ncurses-5.9-x86_64-4.txz in /boot/extra so it's available when I need it (after each reboot) and without having to think why it's not working and how to resolve it.
Of course, one needs to take care that a newer version of ncurses is not required for some feature of core unraid in a future release...

I think it's probably a job for a wknd for me to recompile v1.20 on my box and keep that in my /boot/extra instead - best of both worlds - no downgrading of ncurses and newer/latest version of iotop :)
