我已经安装了 Tex Live 2016install-tl以获取最新版本，但是我遇到了命令问题tlmgr。如果我使用该命令启动应用程序，
tlmgr -gui
则看不到已安装的软件包：获取的错误是
Tk::Error: /usr/bin/tlmgr: open(/usr/share/texlive/tlpkg/texlive.tlpdb) failed: No such file or directory at /usr/share/texlive/tlpkg/TeXLive/TLPDB.pm line 416.
TeXLive::TLPDB::from_file at /usr/share/texlive/tlpkg/TeXLive/TLPDB.pm line 416
TeXLive::TLPDB::new at /usr/share/texlive/tlpkg/TeXLive/TLPDB.pm line 146
main::reinit_local_tlpdb at /usr/share/texlive/texmf-dist/scripts/texlive/tlmgrgui.pl line 2024
main::update_all_packages at /usr/share/texlive/texmf-dist/scripts/texlive/tlmgrgui.pl line 1970
main::__ANON__ at /usr/share/texlive/texmf-dist/scripts/texlive/tlmgrgui.pl line 436
该texlive.tlpdb文件未安装在/usr/share/texlive/tlpkg/，而是安装在
/root/texmf/tlpkg/texlive.tlpdb
/usr/local/texlive/2016/tlpkg/texlive.tlpdb
我该如何正确重新配置tlmgr才能走正确的路径？谢谢

您可以尝试运行：
sudo tlmgr backup --clean --all
