In Linux (Ubuntu 20.04) I upgraded my Calibre 6.27 to version 7.7.0, or so I suppose, but it still shows version 6.27. I uninstalled it, and ran the upgrade again. I did it using the standard wget command, and then once again using a downloaded tar file that specifically said 7.7.0. I went to the /opt/calibre directory, and watched the uninstall and reinstall happen. I checked the /usr/bin folder and the calibre link to /opt/calibre/calibre. They were all deleted and reinstalled. I ve checked the calibre-gui.desktop files in /usr/share/applications and /usr/local/share/applications, and the first one still shows the original install date, and the second shows the most recent install date. They each have slightly different commands, and I ve run both separately, but neither performs differently. I tried removing the old .desktop file, and copying the new one over it. They both run the calibre link in /usr/bin which points to /opt/calibre/calibre, and the date on opt/calibre is from the latest install. No path is specified in the .desktop file. Maybe its upgraded to 7.7.0, but if it is it still says 6.27. Here s the commands I ran:
sudo -v && wget -nv -O- https://download.calibre-ebook.com/linux-installer.sh | sudo sh /dev/stdin
sudo calibre-uninstall
sudo mkdir -p /opt/calibre && sudo rm -rf /opt/calibre/* && sudo tar xvf / home/lindsey/Dendoloads/calibre-7.7.0-x86_64.txz -C /opt/calibre && sudo /opt/calibre/calibre_postinst
还是说6.27。
我在任何地方都进行了检查,我可以想到另一个安装名录。 当我无动于衷时,我检查一下我是否能够继续从指挥线走下去,我不能。
不管怎么说,它还是说6.27。
