Bug#933053: libncurses6: Ncurses-based Terminal UI Programs Broken in Debian Buster
Control: reassign -1 ncurses-base 6.1-1 Control: retitle -1 rep in xterm* terminfo entries not supported by older terminal emulators On 2019-07-26 13:53 +0800, WHR wrote: > Package: libncurses6 > Version: 6.1+20181013-2 This is not a bug in the library but rather an incompatibility between the xterm* terminfo entries since ncurses 6.1 and several older terminal emulators. It is rather unfortunate that nobody reported it (at least not to the ncurses maintainers) before the buster release. :-( > Severity: important > Tags: a11y > > Hello. > Most TUI programs that based on ncurses in Debian buster seem broken. > Affecting programs aptitude(8), cfdisk(8), iftop(8), nano(1), nmon(1) and > nload(1). > Some screenshots are attached. > May related to bug #905247.

Since so many older terminal emulators are affected, I guess we have to disable the problematic feature in ncurses-base. If you want to do that yourself, the following command should do the trick: infocmp -x | sed 's/rep=[^,]*,//' | tic -x - This writes a new compiled terminfo entry for $TERM under $HOME/.terminfo (or /etc/terminfo, if you are root) which takes precedence over the one in /lib/terminfo. You probably want to remove it once a fixed ncurses-base is available. Cheers, Sven 1. https://bugzilla.gnome.org/show_bug.cgi?id=787701

This makes sence, this explained why the didn't happen in dtterm(1) and tmux(1). 2019-07-26 0:55 GMT-07:00, Thomas Dickey : > On Fri, Jul 26, 2019 at 01:53:21PM +0800, WHR wrote: >> Package: libncurses6 >> Version: 6.1+20181013-2 >> Severity: important >> Tags: a11y >> >> Hello. >> Most TUI programs that based on ncurses in Debian buster seem broken. >> Affecting programs aptitude(8), cfdisk(8), iftop(8), nano(1), nmon(1) and >> nload(1). >> Some screenshots are attached. >> May related to bug #905247. >> Tested with xfce4-terminal 0.8.3 and libvte-2.90-0.36. > > In buster, I have > xfce4-terminal 0.8.3-1 and libvte-2.91-0.46.1-1 > > Perhaps you're using this from an older system, where the terminal > emulators > lacked support for xterm's repeat-control, but set TERM to "xterm" or > something derived from that.

In buster, I have xfce4-terminal 0.8.3-1 and libvte-2.91-0.46.1-1 Perhaps you're using this from an older system, where the terminal emulators lacked support for xterm's repeat-control, but set TERM to "xterm" or something derived from that. If so, that's an old issue from 2017. https://invisible-island.net/ncurses/ncurses.faq.html#xterm_generic -- Thomas E.

Package: libncurses6 Version: 6.1+20181013-2 Severity: important Tags: a11y Hello. Most TUI programs that based on ncurses in Debian buster seem broken. Affecting programs aptitude(8), cfdisk(8), iftop(8), nano(1), nmon(1) and nload(1). Some screenshots are attached. May related to bug #905247. Tested with xfce4-terminal 0.8.3 and libvte-2.90-0.36. Also tested with CDE 2.3.0 dtterm(1) and this issue dosen't seems affect dtterm(1). -- System Information: Debian Release: 10.0 APT prefers stable APT policy: (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.19.0-5-amd64 (SMP w/8 CPU cores) Locale: LANG=C, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE=C (charmap=UTF-8) Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages libncurses6 depends on: ii libc6 2.28-10 ii libtinfo6 6.1+20181013-2 Versions of packages libncurses6 recommends: ii libgpm2 1.20.7-5 libncurses6 suggests no packages. -- no debconf information
