我正在尝试更新 Texlive 来update-tlmgr-latest.sh解决以下问题：
/usr/bin/tlmgr: unexpected return value from verify_checksum: -5
但kpsewhich一直返回/并且我不知道如何让它工作。
$ kpsewhich --var-value=SELFAUTOPARENT
/
update-tlmgr-latest.sh 错误：
sudo env PATH="$PATH" ~/Downloads/update-tlmgr-latest.sh
[sudo] password for *:
Verifying archive integrity... All good.
Uncompressing TeX Live Manager Updater 100%
./runme.sh: Cannot find TeX Live root using kpsewhich --var-value=SELFAUTOPARENT.
./runme.sh: (no tlpkg/texlive.tlpdb and/or tlpkg/tlpobj/.)
./runme.sh: Please set your PATH as needed, otherwise it's hopeless.
输出tlmgr conf：
tlmgr conf
(running on Debian, switching to user mode!)

==== kpathsea variables from environment only (ok if no output here) ====
答案1
正如@Sati 在对该问题的评论中提到的那样，sudo apt upgrade texlive*修复了这个问题
