Can I have the terminal type as well as terminal configuration and value of TERM variable?
Unfortunately not easily. It's essentially a random failure, which indicates a race condition. It's not easily reproducible.
Also the ncurses version/changlog info of the affected system?
This issue occurs in tests from a while ago, so I don't think the version helps much.
I need information otherwise I can do exactly nothing. It should be possible to take a snapshot of the QA system to allow to logon -- You are receiving this mail because: You are on the CC list for the bug.

The values set /etc/sysconfig/console like CONSOLE_FONT, CONSOLE_MAGIC, CONSOLE_ENCODING, The value TERM on the console (should be linux and not old cons25 or similar) Please be aware that the nurses API use a escape sequence to switch line graphics mode on and off of the used console font. If you are using the option --ascii-lines ... like dialog --ascii-lines --yesno yesno 5 30 then the real characters are shown as it are defined and shown in man:terminfo(5) at section `Line Graphics` at the table in column `Ascii Default` ... and as this works with the ACS characters acsc=++\,\,--..00``aaffgghhiijjkkllmmnnooppqqrrssttuuvvwwxxyyzz{{||}}~~, in new TERM=linux as I've seen on the console it is very likly that this is not an error of ncurses.

Hmmm ... it could be a problem with qemu and its EGA/VGA console emulation and it this happens randomly this smells like not initialized start values for the font character mapping -- You are receiving this mail because: You are on the CC list for the bug.

Maybe I should write a simple shell script to check with help of TERM, if the terminfo descriptions fits to the used terminal line/device, and using tput to check the line graphics as well.

This is not aarch64 specific and happens on x86_64 as well.
But with qemu I guess ... or has this ever been seen on real hardware?
/dev/ttyAMA0 is a serial which is not used for this test.
OK, taken
Given the randomness, I would go for a broken console font setup, likely due to some race conditions. How should we check this?
I would search for a wrong console font setup, that is with wrong UTF-8 line glyphs as this dialog program uses ncursesw and hence uses UTF-8 glyphs. -- You are receiving this mail because: You are on the CC list for the bug.

That are the values set in /etc/sysconfig/console like CONSOLE_FONT, CONSOLE_MAGIC, and CONSOLE_ENCODING. Then to check if the font loaded does include the required line glyphs, e.g. by using exactly this font on a hardware system, and if this works then to check the VGS/EGA implementation of qemu at https://github.com/qemu/qemu/blob/master/ui/curses.c -- You are receiving this mail because: You are on the CC list for the bug.

To debug this it would be very helpful to see if the console font and its mapping on the current terminal device line is configured correct.
For this I'd like to propose the command sequence
tty tput init echo -en '\x0elqqqqqqqqqqk\x0f\n' . /etc/sysconfig/console echo $CONSOLE_FONT find /usr/share/kbd/consolefonts/ -name "${CONSOLE_FONT}*" loadunimap -o old.uni lat1 grep 'U\+2500' old.uni echo -en '\x0elqqqqqqqqqqk\x0f\n'

old.uni
to see what mapping is really loaded. This mapping is used to get the correct eight bit byte line glyph of the loaded font on the multi byte character line glyph as well as on the alternates characters set (ACS) line glyp

I need to run this on an affected system, but this is not easily reproducable. So, it take times.

This has been seen on some openQA qemu runs. This might be a race condition, triggered more often in openQA qemu.
