1. Tried to update from v6.26 | After error above removed phpmyadmin via dietpi-software and tried to install again - same error

Expected behaviour

phpmyadmin should install without error

Actual behaviour

phpmadmin fails with cannot overwrite non-directory '/var/www/phpmyadmin' with directory pMyAdmin-5.0.0-english

Lighthttd fails to start because of 50-myphpadmin.conf doesnt exist

Extra details

I tried to sent report from the error-handler but terminal closed after it did something. Dunno if actually sent anything. First time doing a report, also attached bug report ID, maybe report went through

@Nightliss
Many thanks for your report.

Hmm strange, I tried fresh install an reinstall and both works very well, hence at least no syntax bug.
It should no be related, but could you try the following:

sed -i 's/target="-d \$target"/target="-d\$target"/' /DietPi/dietpi/dietpi-software
dietpi-software reinstall 90

Hi,
just a stupid thing but if I read the error message above, it's stating cannot overwrite non-directory with directory. Means /var/www/phpmyadmin is a file. Isn't it?

Pls can you past output of

cd /var/www/
ls -l

[Nightliss]

Hey @Joulinar, here is the result, seems it's symlinked?

[Joulinar]

pls can you try to remove the symlink. it should be a directory

root@DietPiVM1:/var/www# ls -l
insgesamt 76
-rw-r--r--  1 root root 37984 Jan  3 11:04 apc.php
-rw-r--r--  1 root root  3388 Jan  3 10:59 index.lighttpd.html
-rw-r--r--  1 root root 22915 Jan  3 11:04 opcache.php
-rw-r--r--  1 root root    20 Jan  3 11:04 phpinfo.php
drwxr-xr-x 11 root root  4096 Jan  3 11:04 phpmyadmin
root@DietPiVM1:/var/www#

@Joulinar,

that helped, phpmyadmin installed correctly. Somehow it didn't occur to me to try a remove the symlink. Many thanks for help :)

PS: Had no idea that overwriting a symlink would be a problem for the os.

@Nightliss
Ah you're right. In case of Nginx and Lighttpd we previously placed symlinks and I guess the installer does not correctly remove them, but only directories. I'll fix that and release a small hotfix release v6.28, as there have been some other small bugs appeared (small code changes, easy to fix).

Fixed with: https://github.com/MichaIng/DietPi/commit/9c80f04302456000172057c85be33d877e4db5fa (whoopsie commit got wrong version string 😅)

[MichaIng]

v6.28 is out, I mark this issue as closed.
