Manjaro install ncurses5-compat-libs

Question

I'm trying to install this package ncurses5-compat-libs but I can because of the following problem.

What I did:

1. yay ncurses5-compat-libs

There are 2 types of errors: Either I will check 'Y' and I will add the key, so in this case, I will receive the error message as follow

gpg: keyserver receive failed: Permission denied
==> Error: Problem importing keys

Or I will check as 'n' to don't add the key and I will receive

==> Verifying source file signatures with gpg...
    ncurses-6.1.tar.gz ... FAILED (unknown public key 702353E0F7E48EDB)
==> ERROR: One or more PGP signatures could not be verified!
Error downloading sources: ncurses5-compat-libs

2. sudo gpg --recv-keys C52048C0C0748FEE227D47A2702353E0F7E48EDB

I've tried to add it manually but it didn't work.

3. sudo gpg --recv-keys 702353E0F7E48EDB

Also this one I've tried to add it manually but it didn't work

4. yay -S --noconfirm --needed ncurses5-compat-libs

5. Trying to fallow this forum

and least but not last

6. I've tried to clone the repository by hand by following

git clone http://aur.archlinux.org/ncurses5-compat-libs.git 
cd ncurses5-compat-libs
sudo gpg --recv-keys C52048C0C0748FEE227D47A2702353E0F7E48EDB
makepkg -sic
cd ..
sudo rm -r ncurses5-compat-libs

And guess what, I'm back from where I started...

==> Verifying source file signatures with gpg...
    ncurses-6.1.tar.gz ... FAILED (unknown public key 702353E0F7E48EDB)
==> ERROR: One or more PGP signatures could not be verified!

Dose any of you guys have any idea how can I fix this problem? If so let me know because I'm getting crazy already not been able to fix this.

Answer 1

You shouldn't need specifically ncurses5-compat-libs if you have a higher version of ncurses. Because version 6 is backwards compatible with version 5. You need to check whether you have libtinfo.so.6 or not. If you have it then you just need to create a system link. Check if you have libtinfo.so.6, so Run:

ls /lib/ | grep libtinfo

if you can't see libtinfo.so.6, you need to install ncurses (the current latest version of it: 6.2) and then create a system link that I mentioned below. so run:

sudo pacman -S ncurses
sudo pacman -S lib32-ncurses

if you have libtinfo.so.6 then run:

sudo link /lib/libtinfo.so.6 /lib/libtinfo.so.5

For me sudo link /lib/libncursesw.so.6.2 /lib/libncurses.so.5 fixed the issues. Using v6 and relying on v5-backwards-compatibility seems to be the best solution. – Humber

Answer 2

I went a step further from creating the link in the other answer here:

sudo link /lib/libtinfo.so.6 /lib/libtinfo.so.5

And created a dummy package so I could build something that depended on that being a thing:

$ cat /opt/aur/ncurses5-compat-libs-dummy/PKGBUILD
pkgname='ncurses5-compat-libs'
pkgver=6.1
pkgrel=1
arch=(any)
provides=('libtinfo5')

$ cd /opt/aur/ncurses5-compat-libs/dummy
$ makepkg -si

worked like a charm
