I meet the same bug. I use Buster 10.7, I installed XFCE,MATE,GNOME desktop in my computer. But this bug only occur in XFCE, MATE and GNOME is no problem. BTW: dbus-x11 is already installed in my compurter. I also strace the pid of gdebi-gtk, the last error lines is following: mprotect(0x7f6abcb42000, 4096, PROT_READ) = 0 mprotect(0x7f6abc710000, 4096, PROT_READ) = 0 mprotect(0x7f6abc6ff000, 32768, PROT_READ) = 0 mprotect(0x7f6abc7b4000, 4096, PROT_READ) = 0 mprotect(0x7f6abc9ce000, 4096, PROT_READ) = 0 mprotect(0x7f6abc9af000, 4096, PROT_READ) = 0 mprotect(0x7f6abcb53000, 4096, PROT_READ) = 0 mprotect(0x55c84fb26000, 4096, PROT_READ) = 0 mprotect(0x7f6abcba2000, 4096, PROT_READ) = 0 munmap(0x7f6abcb57000, 147011) = 0 set_tid_address(0x7f6abbcfa810) = 25973 set_robust_list(0x7f6abbcfa820, 24) = 0 rt_sigaction(SIGRTMIN, {sa_handler=0x7f6abc9896b0, sa_mask=[], sa_flags=SA_RESTORER|SA_SIGINFO, sa_restorer=0x7f6abc995730}, NULL, 8) = 0 rt_sigaction(SIGRT_1, {sa_handler=0x7f6abc989740, sa_mask=[], sa_flags=SA_RESTORER|SA_RESTART|SA_SIGINFO, sa_restorer=0x7f6abc995730}, NULL, 8) = 0 rt_sigprocmask(SIG_UNBLOCK, [RTMIN RT_1], NULL, 8) = 0 prlimit64(0, RLIMIT_STACK, NULL, {rlim_cur=8192*1024, rlim_max=RLIM64_INFINITY}) = 0 brk(NULL) = 0x55c851978000 brk(0x55c851999000) = 0x55c851999000 statfs("/sys/fs/selinux", 0x7ffd9c0c23b0) = -1 ENOENT (No such file or directory) statfs("/selinux", 0x7ffd9c0c23b0) = -1 ENOENT (No such file or directory) openat(AT_FDCWD, "/proc/filesystems", O_RDONLY|O_CLOEXEC) = 3 fstat(3, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0 read(3, "nodev\tsysfs\nnodev\trootfs\nnodev\tr"..., 1024) = 377 read(3, "", 1024) = 0 close(3) = 0 access("/etc/selinux/config", F_OK) = -1 ENOENT (No such file or directory) futex(0x7f6abcaedf58, FUTEX_WAKE_PRIVATE, 2147483647) = 0 futex(0x7f6abcaedf58, FUTEX_WAKE_PRIVATE, 2147483647) = 0 geteuid() = 1001 openat(AT_FDCWD, "lib/x86_64-linux-gnu/charset.alias", O_RDONLY) = -1 ENOENT (No such file or directory) openat(AT_FDCWD, "/usr/lib/x86_64-linux-gnu/gconv/gconv-modules.cache", O_RDONLY) = 3 fstat(3, {st_mode=S_IFREG|0644, st_size=26402, ...}) = 0 mmap(NULL, 26402, PROT_READ, MAP_SHARED, 3, 0) = 0x7f6abcb74000 close(3) = 0 futex(0x7f6abc97ca08, FUTEX_WAKE_PRIVATE, 2147483647) = 0 write(2, "pkexec must be setuid root\n", 27) = 27 exit_group(127) = ? +++ exited with 127 +++ Is this bug possible have relation to the selinux ?
