• • 想卸載一個包，發現怎么都卸載不掉，報E: Unable to locate package（后來發現我壓根沒裝這包，我是裝的vsftpd！！！）
  • 20220214

如題：

[root@ubuntu /home/arnold]7# apt-get install update Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package update

解決辦法：


點close，不要點revert（恢復）！


我也不知道解決沒有，，之前最初的指令好像寫錯了，應該是：sudo apt-get update，，中間不需要install，，

現在我是用apt-get install update和apt-get install upgrade倒是正常，，，更新了很多包

但是我后面執行的時候還是發現不行哎！！！

[root@ubuntu /home/arnold]5# apt-get install update Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package update [root@ubuntu /home/arnold]6# [root@ubuntu /home/arnold]6# apt-get install upgrade Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package upgrade

但是我安裝包的時候倒是沒有報那個錯誤！！！

參考文章1：如何從根本上解決E: Unable to locate package錯誤的方法

參考文章2：Ubuntu install 錯誤 E:Unable to locate package

還是解決不了，，，，在網上都找不到關于E: Unable to locate package update（E: Unable to locate package upgrade）的報錯解決方法，全是E: Unable to locate package的！！！！

想卸載一個包，發現怎么都卸載不掉，報E: Unable to locate package（后來發現我壓根沒裝這包，我是裝的vsftpd！！！）

[root@ubuntu /home/arnold]15# apt-get remove vsftp Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package vsftp [root@ubuntu /home/arnold]16#

看來這個問題必須解決才行

我參考 ubuntu18.04 E: Unable to locate package *錯誤 方法試試

• 1、刪除/var/lib/apt/periodic文件夾下所有文件（刪除前先備份）

[root@ubuntu /home/arnold]16# cd /var/lib/apt/periodic/ [root@ubuntu /var/lib/apt/periodic]17# ls download-upgradeable-stamp update-stamp upgrade-stamp unattended-upgrades-stamp update-success-stamp [root@ubuntu /var/lib/apt/periodic]18# cd .. [root@ubuntu /var/lib/apt]19# tar cvzf periodic.tar periodic/ periodic/ periodic/upgrade-stamp periodic/download-upgradeable-stamp periodic/unattended-upgrades-stamp periodic/update-stamp periodic/update-success-stamp [root@ubuntu /var/lib/apt]20# ls cdroms.list extended_states lists periodic daily_lock keyrings mirrors periodic.tar [root@ubuntu /var/lib/apt]21# cd periodic [root@ubuntu /var/lib/apt/periodic]22# rm * -rf [root@ubuntu /var/lib/apt/periodic]23# ls [root@ubuntu /var/lib/apt/periodic]24#

• 2、更換sources.list下載地址
  跳過

暫停暫停！！問題暫時消除

貌似與這個問題有點類似，那個問題成功解決了
